Honestly, (and I know this might seem odd), the most important aspect in choosing a game is who the host is. I look for a host that:

a. has previously started games that I enjoyed
b. has previously (or currently) started games with an interesting premise (I like to RP, for example, so I look for a host that emphasises this)
c. is discriminating when accepting players
d. has actively sought to fill open spots (advertising, not letting the thread drop off the board, etc)
e. has proven understanding and flexible about turn dates (and pushing them back for planned abscenses)

I haven't encountered any player disputes, but I would also look for a host that I had seen handle them well.

I agree with you that the host is important. For example, I would join any game hosted by Imperator Fyron (not to knock anyone else ) because he meets all of the qualifications you've listed. But by the same token, if you don't give someone new a chance...

One of my pet peeves is clicking on a game and there being no description at all! How is that going to attract a player? It won't.
