Oh, I agree there's little 'new' out there. Part of that is that it is very difficult to come up with something that is both new and fun.
But for me, a good rehash of ideas that have been done is just fine. I read at least 100-150 novels a year, and maybe 2 or 3 of them have new ideas or stories. The rest are still entertaining, and to me, that's what I'm looking for more than anything else. So I'll get Divinity:OS, and PoE, and a bunch of other traditional RPGs. And I'll buy Sunless Sea, even though it's just a Lovecraftian-style Roguelike, because it seems to be a well done version.
Of course, there are games I've gotten severely burned on. Civ V and Civ BE are two of the biggest. Pre-ordered both, and regretted it each time. Those were NOT well-done.
I've got to ask, though - what do you play these days?
