--- Comment #5 from Rafał Mużyło galtgendo@o2.pl --- Well, while I'm not really familiar with the engine, that check seemed to be a part of the engine (though likely just some recent version of it as another game of that engine (also a free one) didn't have it).
The check was such that upon running the game executable a popup with 'This game needs VC++ redist...Install it now ? Yes/No' (well, roughly), so to me it looked like an internal engine check (if a silly one), than something game's author had done on their own.
