My review is slightly biased because I've played all the other NMH games in chronological order.

My favorite thing about No More Heroes is the fact that it never fails to make me laugh. Its story and world has always been simultaneously hilariously absurd and really cool, which NMH 3 has in spades but now with a more polished battle system (sadly, a few features missing from old games but still a welcome progression from NMH 1, 2, and my favorite of the series TSA:NMH), a killer BGM (plus surprise musical sections), and more awesome mechs.

My only issue with the game is the truly horrible loot system (Monster Hunter~esque) where the drop rates are very low and sometimes tedious to even start a battle (Special Missions). You basically have to spend an extra 30-50+ hours if you're a completionist.

Aside from that, after playing NMH I've become a fan of Suda51 and Grasshopper Manufacture. Looking forward to playing more games from them.

Suda51's Magnum Opus. Worth every penny especially on sale.
