RULES VIDEO
A heavy Euro-style expert strategy game themed around the Search for Extraterrestrial Intelligence (SETI), where players become astronomers and scientists operating space telescopes and probing the solar system's planets to catch alien signals — an organic engine-building game built on a rondel. Planets actually orbit the sun each round (a rotating board mechanism), so you have to carefully calculate the timing and trajectory when you launch a probe. Combine roughly 200 tech cards to build your own research infrastructure and squeeze every last drop of efficiency from limited resources — a well-made expert-strategy masterpiece that shows brain-burn at its peak.
※Skip it if the group has beginners or newcomers who'll burn out just from the rules explanation, if calculating the shifting planetary orbits and card text every turn stretches playtime past 3 hours with long think-time, or if you want a light, laugh-filled party game driven by dice or banter.

Scores by situation
New faces+−
♡☆☆☆☆ [Awkward / entry barrier] Just teaching the rules takes at least 20 minutes for this heavyweight. Between the flood of science-jargon icons, the tangled systems, and card text overload, bringing this to total beginners or a social-first couples' gathering goes past awkward straight into exhaustion and mental shutdown — the mood can go cold fast.
Close friends+−
♡☆☆☆☆ [Study-hall mode] This 'ultra-focus' game is the polar opposite of a loud, laughing hangout with your friends. Once everyone sits down to calculate orbits and plan card combos, the table turns into a silent study hall with nothing but breathing and dice clicks — absolutely not recommended if your friend group wants dopamine-fueled energy.
Strategy+−
♡♡♡♡♡ [Life-defining masterpiece] The tightly interlocking orbital system and the replayability from its massive card pool are out of this world. The catharsis of your science base coming together perfectly, catching an alien signal, and watching your score explode delivers the ultimate thrill for Euro strategy fans. Any expert strategist should happily pull an all-nighter for this must-play masterpiece.
Couple+−
♡♡☆☆☆ [Quiet healing] The space theme and astronomy components deliver great immersion, and there's no direct, spiteful interaction. But for a couple wanting a chatty, cozy evening, the head-splitting brain-burn and sheer calculation are overwhelming — it feels less like peaceful emotional healing and more like grinding through a suffocating research thesis.
Duel+−
♡♡☆☆☆ [Downtime hell] At 2 players, turns cycle quickly and you can enjoy a tight scoring race, but any skill gap or a single long think stalls the flow and drags the pace down. Since it's a battle of each player optimizing their own engine rather than tense interaction and head-to-head mind games, it doesn't quite deliver that thrilling duel feeling.
Gateway+−
♡☆☆☆☆ [Tier 5 — strongly not recommended] The system sits at the pinnacle of modern strategy games, but the sheer volume of rules, edge cases, and misplay risk make the barrier astronomically high even for an eager, driven newcomer's first strategy game. Better to tackle it after getting solid reps in worker placement and resource management through gateway Euros like Splendor or Stone Age.
