The graphics are pretty good, plus all the characters and storyline. It's pretty much the same game you played back on PS2 but with upgraded graphics and achievements. As for the achievements, they are pretty easy and you can complete the game in around a week if you really are determined. Great for achievements but it's pretty much the same mash button game you'd expect.
-graphics and sound
-Budokai 1 is very difficult, especially controls
-Budokai 3 has moments where the computer dodges too much and causes you to lose or fall out of an arena too much.
You're better off just playing the original versions of these two games that are on this HD Collection. The games on this are ruined completely with horrible replacement soundtracks, poor controls and possibly the worst CPU AI ever.
