It definitely won't play much like any of these games but just know that they're in my head a lot!. Compared to late eighties tile based RPGs, I have less love for the big nineties RPGs like Fallout or like Baldur's Gate. Choice and consequence isn't *that* fascinating to me. I prefer cool systems
lastly, Doom 2's one of my fave games but it is impossible to take influence from without copying, proven over and over again throughout the ages x3
