Reika makes mod by himself for himself. He’s got a very clear idea of where he wants to go and what he wants to do, but he also straight up does not care if his mods do not work outside his dev setup or create problems: see
for a more in-depth explanation by reika himself.
Greg is a modder with a somewhat clear idea of what he wants to do, the willingness and the time to work on it for almost a decade of quite literally learning by doing, so I’m more biased towards him in this case.
The HBM dude is uh
he’s updating his mod and keeps some compat with gt6 so that’s nice I guess? But other than that I can’t really say anything, his mod has some interesting designs but it doesn’t look like what I would play.
