I actually played both in order and found A&D to be way funnier. The biggest laugh I got out of Giants was the "Timmy!" scene. The smallest laugh I had through A&D was "Wait! Give me another chance! It's been a long time since I've kissed a man! I CAN DO BETTER!"

It just got better from there.

Anyway, Planet Moon went on to mostly do PSP and casual Wii games. Infected (PSP) would definitely be worth checking out if you like zombie shooters.

It's on steam, if anyone is interested. It's a brilliantly funny game that I always revisit from time to time. Not sure if there is an online DRM free version available.
