Capcom have always done the best deals of any publisher on Humble Bundle whether it's an individual series or a a mixed spread, well done to them. I'm sure it's brought plenty of people into the franchise, and it's smart to do this with the RE8 DLC coming (or is it here?)
I should do this but I haven't played an RE games since 3 and I'm not talking the remakes.
Do it. It's a great price and you'll get a good spread of gameplay styles.
0/1 for classic (door skip mods exist if they bother you)
4 for a hybrid of old and new (don't forget
RE4HD, which is easy to install and the best texture pack/fan patch I've ever seen)
5 for
chasing 4's success but failing a more action heavy twist on 4
6 for not having a clue and flying too close to the sun
7 for a soft reboot in 1st person with a smaller scope, closer to the original
Revelations 1/2 for a different sort of game (Rev2's Raid mode is fun if nothing else)
2 Remake is fantastic and is what 6 should have been
3 Remake is flawed if you're a big fan of OG 3, but still well worth your time
Even if you just wanted 2R/3R and the rest are just bonuses in case you one day fancy trying one, it's a great price.
