First Person Shooter arnt all bad... but yeah, in general I agree.
It's not even that they're bad. I'm sure Bayonetta, Metal Gear Rising, Devil May Cry 4 and DMC (aside from the character design) are quite good. But because I felt like I had my fill of that genre, it was hard for me to get into the ones I tried after DMC3.
And after playing Yakuza 3 for over 120 hours, I took a 3 year break from the series before starting Yakuza 4.
