So now i kinda curious what the rest of you prefer - play every update, or wait until something similar to full release?
It totally depend of the game, its story, its game mechanism and of the author abilities to release compatible updates. Oh, and also of the author abilities to not restart his game every six months.
If the story is interesting and the updates compatibles, I'll play every updates, or at least one over two updates.
If the game massively rely on free roaming, I'll try it once, then generally wait 4/5 updates, playing it (if it fit the criteria above) once you don't pass half your time visiting empty rooms.
In all other case, including interesting game restarted more than once, I'll perhaps play it when it will be completed, if I remember that it can be an interesting game.
