I recently purchased the MGS DLC Level Kit for LBP. I was quite awesome and well worth the $6.50 i payed for it. It's amazing how they managed to distill the essence of MGS into LBP. On top of that I feel like the stealth was quite fun and worked amazingly well with the layers which most people complain about.
Most importatnly it also gives Sackboy his second power up the Paintinator(1st is Rocketpack). I hope by the time LBP2 or LBPPortable come along that they have enough powerups that can give these sequels even more variety in gameplay. Can anyone think of any other interesting power-ups?
I do however still think that the costumes(at least 1st party based) should be free.
