It sounds like there's some slight bias in your post, just because a few reviewers gave it a low score doesn't mean it isn't well recieved, it's still shipped more copys than any other Capcom game in history, and has more good reviews than those few bad ones. Also noticed that there's more players in support of the game than there is the odd vocal few who are slamming it, most of which haven't even given it a proper chance, like yourself who feels like throwing it out the window. Don't force yourself to play it, you won't enjoy it at all.
It's only shipped 4.5 million copies, but like was said, they wouldn't have shipped so many if there was no demand, the game is clearly doing well on all fronts except a few people like yourself who hate some unfathomed loathing against it.
I've given this game chance after chance but it continues to disappoint me.
I played the Dragons Dogma RE6 demo, it sucked = Strike 1
I played the public demo, it sucked = Strike 2
I played half the main game, it sucks so far = Strike 3
Resident Evil 6......YOU'RE OUT!!!
Hell I hated RE5, but I still enjoyed it more than this.
Whether this game sells good or not I don't care, what I'm happy about is that even if there is more positive reviews, the fact remains that RE6 is the lowest rated game in the main series and has a massive mixed reception among critics, gamers and fans alike so that proves that we will not see another piece of garbage like RE6 again in the franchise, RE7 will have to be something different and the massive action part of the series will be removed due to the Micheal Bay action being one of the most hatred things about it. I see the only options being: taking Resident Evil back to what it's supposed to be or end it entirely, because another sequel with more action than RE6 will just be hated twice as much.
