>>4115424Normal koikatsu and sunshine are essentially standalone versions. Sunshine runs on a newer version of unity, but the modding scene in there is pretty stagnant, while the OG koikatsu still goes strong.
So, to alleviate confusion, i advise you to download the RX14 version. Or whichever is the highest at that moment of time.
Good luck to you, whenever you start. It can be confusing, sure, but so is everything.
