At the end of last year, Sony kickstarted its: "Only on PSN" marketing campaign. One of the best parts of this campaign, other than the great games that were released exclusively on the PSN, was the long-awaited introduction of Playstation 2 Classics on the network. With Sony removing backwards compatibility from most of the Playstation 3 models starting in late 2007, many gamers, including myself, were clamoring for Sony to release PS2 games in a format that we could enjoy. Starting in 2009 with the release of the God of War collection, Sony started to re-make/port many of it's best PS2 games to PS3 blu-rays, usually with trophy support. Though these collections have been a hit, there are hundreds of games from the PS2 backlog that would benefit from a second life on the network. Here are our top 5, in no particular order.
