Eurogamer reports that Sony is refunding gamers who purchased Spyro 2: Gateway of Glimmer and MediEvil following "significant technical issues." In essence, the games were broken. People will have their purchase refunded to them in the next seven days.
There's still no word yet on whether Crash Bandicoot 2 will also have a refund following its removal from the PlayStation store. It's not like XBLA has been immune to bug issues, most notable were the Mad Tracks "stuck in demo" bug and Contra's out-of-sync co-op. Just another day in the land of QA. Someone should make a musical about it.
