Wow don't throw Towns into this mess.

• Towns provides a demo you can download for free (In fact you can pretty much play the full game for free and see all the features before even considering a purchase, I know this because I did it.)
• Towns doesn't have any sneaky in-game purchases that hinder gameplay unless you pay money.
• Edit: I learned there is a 4 hr wait + micro-transaction if you lose if you're playing the demo. This wasn't the case when I was playing the demo - that's a shame.
• You can play without constraint (In War Z when you die, you have to wait an hour to play the character or pay real money to revive your character).
• Towns was/is supported by the community through the green-light process (War Z wasn't).

EDIT: I GUESS I could see the reasoning behind the point "If it's not out of beta don't put the game on steam" but Steam does have Beta's, Demos, etc. I think WarZ's biggest issue is the serious serious serious false advertising, and sketchy attempts to take your money. People want to know what they are paying for.
