Definitely patiently wait for full release with intended outcome. I tend to wait one or even two years with playing new single player games (even those i'm really hyped about) - till all dlcs are out, everything was patched and Definitive Edition released. With Pantheon I don't really want to wait and thats one of several reasons why I've pledged (right now for beta, but I plan to upgrade for alpha soon-ish). As someone stated before different things are expected from different stages of development. I want to be able to play alpha (where I expect multitude of bugs) as soon as possible, but at full release the game should be almost flawless and this moment can not be rushed.
