I enjoyed RE5 quite a bit, but it is in no way better than RE4 (my favorite game last gen, yeah I said it). At all. There was no sense of urgency or immediacy whatsoever in RE5, whereas RE4 was constantly engaging and at times overbearingly intense. Also, your "partner" in RE4 was not intrusive. Yeah, you could do co-op in RE5, but if you weren't, the game was miserable because Ashley was fucking stupid.
And Uncharted sucked.
