Talk about your slow weeks in game releases. I guess this is good news as it allows more time to finish the new Harry Potter book or work your way up the ladder in Battlefield 2
PC - Asheron's Call: Throne of Destiny
DS - Nanostray
PS2 - Colosseum: Road to Freedom, Jackie Chan Adventures
I really can't recommend any of these to add to your collection but Colosseum looks like it might be a decent rental.
