Because you have more to work with when making a game exclusively for the PS3. On top of that Vesperia was garbage anyways. Just give me the PS3 exclusive Tales game & Graces.
I got DA:O on PS3 and it was a good game. The only problem I had with it was the constant auto-saving in Orzammar when exiting a building but once I turned off auto-saving it was fine. DA2 is looking even better and it will be a day 1 buy for me.
But to be fair, it's a Crapcom game so it would've been mediocre regardless if Ninja Theory worked on it or not. Both companies are meh. Hopefully Sony gets a good studio to make Heavenly Sword 2.
Walk down hallways for 40 hours with repetitive gameplay such as "fight monsters, watch cutscene, fight monsters, watch cutscene, fight boss, watch cutscene, fight monsters". Then when you finally think you're getting out into the open world you finally realize that there is no open world, just a slightly bigger dungeon in an outdoor environment. But wait, you have side quests! However, all those "side quests" consist of...FIGHTING MORE MONSTERS!
