It's weird that we haven't seen this happen before (to my knowledge), but I think this is the first non-flat Breakout clone to hit Nintendo's handheld. It's nothing revolutionary, but it does make the experience feel fresher to see your ball breaking down structures with actual height. And there are loads of power-ups to play around with too, with several varieties of guns, paddle size modifiers and ball upgrades to keep you busy.
The soundtrack is nothing sensational and the visuals are a little rough around the edges, but 1001 BlockBusters ends up feeling like a fun little DSi diversion even so. And you can't beat the value, either – it's only two bucks to buy, and the title's claim of 1001 different levels is legit.
