코리올리스 vs 에일리언 RPG: 우주 호러와 아라비안 나이트 SF 비교

빠른 답변

그룹이 카운트다운 시계와 높은 사망 확률을 동반한 서바이벌 호러를 원한다면 Alien RPG를 선택하세요. 정치적 음모, 무역, 그리고 천일야화에서 영감을 받은 생생한 배경에서 더 느리고 개인적인 위험이 펼쳐지는 게임을 원한다면 Coriolis: The Third Horizon을 선택하세요. 둘 다 Free League의 Year Zero 엔진을 사용하므로, 진짜 결정은 규칙이 아니라 분위기입니다.

Coriolis: The Third Horizon과 Alien RPG는 둘 다 Free League의 우주 RPG이며, 둘 다 Year Zero 엔진 버전으로 실행됩니다. 그 공유된 DNA는 비교를 더 부드럽게 만들지 않고 더 선명하게 만듭니다: 주사위 풀을 걷어내면, 당신은 테이블에서 두 가지 매우 다른 약속 사이에서 선택하게 됩니다. 하나는 우주 속의 유령의 집 이야기입니다. 다른 하나는 거대하고 파벌이 주도하는 샌드박스입니다.

이 비교는 각 게임이 그룹에게 실제로 요구하는 것, 즉 플레이어가 세션마다 하는 일, 규칙이 얼마나 치명적인지, 게임 마스터가 맡게 될 캠페인 준비의 종류에 집중합니다. 여러분의 테이블이 다음 6개월을 어디에 쓸지 결정하는 중이라면, 아래의 트레이드오프가 선택을 더 명확하게 만들어 줄 것입니다.

분위기와 전제: 공포 대 음모

Alien RPG는 영화 특유의 공포, 즉 고립된 승무원, 기업의 압박, 협상하지 않는 위협을 중심으로 설계되었습니다. 공개된 시나리오는 플레이어를 제한된 고위험 상황에 몰아넣는 경향이 있으며, 문제는 일이 잘못될지 여부가 아니라 얼마나 빨리 잘못될지입니다. 이러한 초점은 칼로 자를 수 있을 만큼 팽팽한 긴장감을 좋아하는 그룹에게는 강점이지만, 장기적인 정치적 플레이를 원한다면 한계가 됩니다.

Coriolis: The Third Horizon takes the opposite approach. The setting is a cluster of star systems shaped by faith, trade, and old rivalries, with a strong Middle Eastern and North African aesthetic rather than the usual Western space-opera defaults. Campaigns often revolve around a ship, a crew, and the deals they make. Horror exists, but it is one flavor among many.

• If your group argues about who gets the last escape pod, Alien RPG is already speaking your language.
• If your group argues about who owes whom a favor, Coriolis is the better fit.

Rules and lethality at the table

Both games use dice pools of base dice and skill dice, and both let you push a roll for a better result at a cost. In Alien RPG, that cost is often stress, and stress feeds back into the dice in ways that can spiral. The system is designed to make characters fragile and decisions heavy. Combat is fast and punishing, and a single bad round can end a character.

Coriolis uses a similar push mechanic but with a different currency: you can reroll by taking a Darkness Point for the GM, which builds a pool the GM spends to complicate the crew's lives. It is less immediately lethal and more about accumulating trouble. Characters are still mortal, but the game gives you more room to negotiate, scheme, and retreat.

• Alien RPG rewards players who plan exits before they need them.
• Coriolis rewards players who keep a favor in reserve for when the GM spends Darkness Points.

What a campaign actually looks like

An Alien RPG campaign is usually a sequence of jobs or missions, each with its own pressure cooker. The game supports this well, and the cinematic mode is explicitly built for one-shot survival horror. A long campaign is possible, but the tone tends to stay grim, and character turnover can be high. That is a feature for some groups and a dealbreaker for others.

Coriolis: The Third Horizon is built for a crew with a ship and a route. Trade, exploration, faction politics, and personal agendas all have room to breathe. The Third Horizon guide material expands the setting's factions and mysteries, which gives a GM plenty of hooks without requiring a single metaplot. The trade-off is that the game asks more of the GM up front: you need to decide what the crew is chasing.

• Alien RPG is easier to run as a pick-up game or a short arc.
• Coriolis rewards a session zero where the group agrees on a ship, a home port, and a shared goal.

Where the Free League catalog helps

Both games sit in a broad Free League space RPG lineup, and the supporting products matter for the comparison. Alien RPG has a strong line of supplements and scenarios that lean into its horror premise. Coriolis: The Third Horizon has setting and campaign books that deepen the cluster's politics and mysteries. If you already own one, the other is not redundant: they scratch different itches.

A practical way to test the waters is to run a one-shot in each before committing to a campaign. Alien RPG's cinematic scenarios are designed for exactly that. For Coriolis, a single job with a ship, a patron, and one faction breathing down the crew's neck will tell you whether the table wants that kind of long game.

• Run Alien RPG first if your group is new to horror and wants a contained experience.
• Run Coriolis first if your group likes to talk its way out of trouble.

Trade-offs to weigh before you choose

• Lethality versus longevity: Alien RPG is built for high-stakes, high-mortality play, which makes every session tense but can burn through characters fast. Coriolis is less immediately deadly and better suited to a long campaign with the same crew. Pick Alien RPG for a short, sharp arc. Pick Coriolis for a campaign you want to run for a year.
• GM prep burden: Alien RPG scenarios often come with a clear structure and a ticking clock, so prep is contained. Coriolis gives you a sandbox and expects you to decide what the crew is chasing, which is more work up front but more freedom later. If you are a new GM, Alien RPG is the gentler on-ramp. If you like building factions and maps, Coriolis pays off.
• Player buy-in: Alien RPG asks players to accept that their characters may not survive, and to enjoy that pressure. Coriolis asks players to invest in a setting with its own cultures, faiths, and politics, which is a different kind of commitment. Ask your group which pitch excites them more before you buy either book.

Products that support each side of the comparison

• Star Trek Adventures - Second Edition - Starter Set: A starter set for the Star Trek Adventures roleplaying game, taking you to the final frontier to explore strange new worlds and encounter alien life-forms. If your group wants optimistic exploration rather than horror or intrigue, this is the third option worth considering before you commit to either Coriolis or Alien RPG.
• Achtung! Cthulhu 2d20: Shadows of Atlantis 2d20 Edition: A globe-spanning adventure that takes you from the dawn of the Secret War to the fall of ancient Atlantis, beginning with the mysterious disappearance of Dr. Botho Ehrlichmann in the summer of 1939. If you like the idea of cosmic horror but want a historical rather than space setting, this adventure shows how the same dread can play out on Earth.

Which game fits your table?

Best for

• Groups who want survival horror with a clear, escalating threat and are comfortable with character death.
• Game Masters who prefer structured scenarios and a contained prep loop.
• Players who enjoy resource management under pressure, including stress and panic mechanics.

Not for

• Groups who want a long-running campaign with the same characters and a slower burn.
• Players who prefer negotiation, trade, and politics over immediate physical danger.
• Tables that dislike horror tropes or want a more optimistic tone in their space RPG.

Coriolis: The Third Horizon and Alien RPG are not competitors so much as two different moods from the same publisher. If you want dread, pick Alien RPG. If you want a crew, a ship, and a cluster full of debts and secrets, pick Coriolis. Run a one-shot of each if you can, and let the table decide which one it wants to live in.
