Ok so i downloaded this game today.
Cost me 10 Euros,
It is a hell of a lot of fun, it just really looks like shit tho.
The funny thing about the game is when the designer released this payed Alpha test stage at 10 euros a pop, paypal actualy suspended his account because they thought that when he recieved over 600000 Euros he must be doing something dodgey.
As i said it cost 10 euros at the moment but that will cover all current and future content and he is planing on raising the cost to 20 euros when it goes to beta. Apparently he does weekly updates.
Here is the website.
