Congrats to everyone who completed this game 100 %. Definitely not an easy task. I got all achievements the month this game came out (june 2008), in fact it was my very first game I got all achievements for. You could say I'm sort of a DBZ game fanatic.
It's easily my favorite 1000/1000 game... this game is pretty brutal. You'll need a lot of skill with the character you main, in my case it was Bardock, or really exploit the AI if you want to stand a chance. But it's definitely doable and very rewarding when you get the 1000/1000.
RB1 also isn't the easiest because of that All Ruined achievement.
RB2 is very easy though... that's a shame if you ask me.
Had some nice memories of this game haha.
