Just beat Deus Ex: Human Revolution. I really loved it at first despite some simplifications here and there, but towards the end the storyline went from shallow rehash to total shit. I am in serious disbelief in those endings. No resolution, no further information about the assorted characters you interacted with, no attempt to lead into the original Deus Ex. Fucking Nelson Mandela signs even. I mean, what the fuck? This was an ~8/10 game before that and now I'm just irritated. Invisible War was much worse on many fronts, but at least the story was solid and some characters memorable. Next time I play it I'm just going to kill everything and maybe cheat in a lot of grenade launcher ammo (if possible) just because.
EDIT: Although to be fair I only watched one and a half endings. The first one I watched was the fuck-everyone ending, but I reconciled its uselessness with the fact that it was supposed to be mysterious. Then I tried the augz-r-gud ending and rage-quit halfway through. Maybe the others were better, but I doubt it.
