I think I may have answered this question in a different thread, but recently Neuron has topped my list. I posted a rather long review in a comment, so I won't repeat everything I said, but basically I recommend it to anyone. It can get challenging and really fun, but I think even children would enjoy it. It's also one of the few arena games I've played that isn't all about blood and gore. I would even hesitate to call it violent. It really is my favorite game on AG.
