>Tales games on co-op
Still playing them nowadays with my brother. Fun times - having a laugh at skits and weird plot twists followed by crazy comboing and getting stomped on by bosses.
>Mario Party
Haven't played many of them to be honest, but did give it a few whirls with bro and school buddies.
>Dokapon Kingdom
Move aside, Mario Party - this is the shit. Played a lot of it with uni friends and bro. This is the true 'friendship destroyer', even Atlus said in their marketing.
>Crash Bash, Crash Team Racing
The reason to own a multitap for the PS1 (aside from Tales of Eternia/Destiny I suppose…) Here's hoping that Nitro-Fueled does it justice, and Crash Bash remaster is on the way
>Goldeneye
The n64 original I only played at a cousin's house. The Wii reimagining however, did see some constant use when I finally had enough controllers to mix and match. Got even a few school friends that don't play vidya to join. (Sucks that the PS3 version doesn't allow controller mix-matching, and motion control is only available on singleplayer).
>Beat 'em ups
A classic. SOR2, SORR, Scott Pilgrim (thank god for CFW).
