Actually this is an excellent zombie RPG for the price, and I would recommend it. The Alpha did not have much content but it was fun to try out. The Beta has added a lot of new content. I find the combat in Dead State to be a little more challenging than Wasteland 2's combat. (Hopefully W2 will improve in final.) The individual scene graphic detail is also very high quality.
I would wait to start a new game until the first beta patch arrives. Currently there is a random savegame bug and a rapidly inflating log file that causes pauses in combat, but they are already on to it.
They are also adding the ability to unload ammo for those that like to unload the few odd rounds in picked up weapons which was irritating. Just one of many items being added as they go.
I am a big fan of Fallout 1, 2, Tactics and Jagged Alliance, and though this is not a replacement it has been a breath of fresh air in comparison to many other titles in recent years.
If you do not hop onto the Beta, I would definitely check it out on final release.
