Finished Leon's campaign last night. It wasn't quite as bad as I was expecting, but man, this is just not a good game. At several points I felt insulted and confounded by the notion that a team of developers/actual thinking, breathing human beings actually thought certain parts of it would be fun to play. The undying-boss-fest that ends Leon's campaign is so tedious and super-long that it borders on self-parody (particularly when I lost the internet connection partway through with my partner and had to start again several sections back).
More than that, I just don't like most of the tweaks to the gameplay/UI. The herb-mixing healing mechanic is so laughably complicated that it feels like the game is playing a joke on you and will reveal the real healing system any time now. The cover system is clunky, confusing, and mostly useless (at least in Leon's campaign). Weapon selection is cumbersome and time-consuming, due to giving you too many guns and no longer allowing you to assign specific weapons to D-pad shortcuts. Also, both players each get every weapon you find, meaning you lose a bit of the strategy of RE5 in planning each player's loadout. I also preferred the stricter but more predictable melee combat of RE4/5, but thinking about it I'd be fine with how it is in RE6 if they'd go back to labeling the name of the melee move in the prompt. As it is, they throw up the same generic "R1" prompt whether you're near a standing enemy, kneeling enemy, enemy from behind, or a freakin' box. I love running up to an enemy thinking I'm going to obliterate their head with a jumping bulldog, but instead limply shin-kicking a box open and consequently getting my face murdered into stick-waggling QTE Hell.
That's not to say there aren't moments of fun to be had, and in general it's fun enough with a partner, though I bet there will be sections where both of you just want to quit. But on the whole the game feels a bit like going on a date with an ex from five years ago, where you're honestly, perhaps a bit desperately, trying to recapture some of that old spark, while doing your level best to ignore the fact that sometime over the past half-decade she turned into a boring goddamn idiot.
Not overly looking forward to Chris and Jake's campaigns, but dutifully complete them I shall.
