The combat is shit and there is no reason to perform well. You get the same XP no matter what. Boy is a little bitch. The game is garbage. Yeah, it looks pretty. Beauty is only skin deep.
Also, his videos on Doom Eternal are fantastic and really show how the games systems work. The old GoW games have great systems. The new one is trash with boring systems, boring enemies, boring puzzles, boring story, bloated inventory/loot. Fuck GoW 2018. Cookie-cutter shit. And he put in well over a hundred hours, so not like he just dismissed it.
