So there have been a few games I loved to play that were Minecraft, but also different.
1: was a zombie survival wave based where you kill zombies and earn coins to buy guns and use a chest to generate a random gun etc.. you could repair barricades to slow down the zombies.. I think this one had it's own custom launcher..
2: was a restaurant simulator of sort with 3d models. for a singleplayer to enjoy as something to do.. I think it may of had it's own texture, but I could be mistaken..
