Yes Flatflyer, Bohemia Interactive the creators of the Arma series (which by the way also had the ability to buy the game in alpha for a lesser cost) are making dayz a cash grab
Im just gonna assume this is sarcasm even though its hard to tell sarcasm from text.
It is a cash grab, and Bohemia is just using the whole "its so expensive cause we want a small amount of testers" to cover up the fact it is. and when anyone tries to tell people that the price is too steep for a buggy game they and the fanbase can easily say "But its in alpha!" to cover that up too.
Really the only difference I've seen from the mod to the standalone is just they've made the engine a bit better for it (even though a few bugs from the mod are still there.) and a few expansions to the map and making melee weps useful. That isn't enough to make this a game worth retail price.
