There is a sale going on near me where certain PS2 titles are going for €15 each and €30 for three of them. Could grab Bully, BT3 and BT2 for €30 but I am not sure if BT2 is any different from BT3.

I'v only played the second title a few times so I am wondering if the Budokai T. games are like sports games: the 08 edition better slightly so no pointing buying last year's edition.

Perhaps I should get BT3 on its own for €15 and get Bully elsewhere for €10 secondhand...

BT2 actually has better gameplay than BT3, they overdid it (and killed some pretty good features of-) BT2. BT3 has more characters though. If you haven't played any, then the changes to gameplay in BT3 aren't going to be noticeable, so it won't be something you can hold against it without playing the second. That in mind, you might want to just stick with BT3 if you're hard on cash.

BT2 is way! way!better than BT3

nar 3 is better
