Colobot Forum - International Colobot Community

I'm curious, guys from which country made that game? Somewhere in google i found that Epsitec is a Czech company, but alot of Polish language near colobot + colobot have most popular World-wide languages and.... PL? So who made this game, Polish, or Czech?

EPSITEC is actually a Swiss company, not Czech. But TerranovaTeam consist mostly of Polish fans who made this community. Rest of our history you can find here:
