Bleach(skip Bounto Arc, it's so pointless lol)
Naruto up to episode 135, then watch Naruto Shippuuden, which takes place 2 or 3 years after Naruto
Chrono Crusade
Trigun
Outlaw Star
Gundam series
And for 2 game related animes
Devil May Cry. It's 12 episodes long and is like a mini-series within itself. Many episodes are slightly related, but it's still awesome.
Last Order - Final Fantasy VII
