So I just finished watching this anime called Hi Scoool! SeHa Girls. It's pretty much a show where Sega Consoles are personified into these school girls who have to travel to these worlds of Sega games. Lots of references for Sega Genesis to Sega Dreamcast with a few newer Sega games such as an arcade game, a mobile phone game and a DS game.
If the idea of watching an anime centered around some school girls is a turn off to ya it's more in the vein of Digi Charat, Azu Manga Daioh, and Cromartie High School. It's really fun, if you're a fan of any of the Sega Consoles you owe it to yourself to give it a shot, atleast watch the first two episodes, they're like 10 minutes a piece and you can tell the people who worked on it had a lot of love for Sega.
Seriously, I haven't seen them put so much Sega love into something since they made Segagaga back on the Dreamcast (They also throw in the Segagaga Theme song along with a bunch of other Sega tunes.
