Huh? save game locations are to be put into a user specific folder, not the game folder.
Sorry, I was not clear, the actual save file is in a user local folder, but a huge portion of the game is procedurally generated, thus needs to be cached. Whether I could also save that in a user folder or not is a good question, I think it would be better to not do that so the loading time would be only in the first time anyone runs the game.
limitation of some engine
That's the reason I've seen dev. complaining in another thread in steam, I'm making my own engine so reinventing the wheel some times with more flexibility is a common thing to me.
And yes, I really don't think my game will even be larger than 1GB, as I said most of the data is procedurally generated in the first time you run it, so the actual download size will not be that big.
