Uh... wrong. This is pre-alpha stage, there\'s no combat yet, and the next release will most likely be Alpha. It will be years till we see Gold at all.
PS will stay free throughout its lifetime however.
About your PC restarting: I have no idea what kind of specs you have, but occasional random reboots are a classic sign of an overheating CPU. Do something to cool your computer down while playing graphically intensive games and see if that helps. If it does, I advise that you consider investing in additional fans or heatsinks for your machine.
