I play it once in a while. It's a fun enough substitute for a real Elder Scrolls game. I'm pretty antisocial when playing, so can't comment on how good the community is, but the wife has made a number of PSN friends through it, and there seems to be a ton of people on it. The biggest hurtle for me to clear was realizing I couldn't play it like ES3-5, you absolutely have to quest to get good stuff, and there is no point in filling your inventory since so much has 0 GP sale value.

ESO has both text and voice chat - as soon as you get a crew together, I'd suggest turning off in-game chat and use party chat...nothing sucks more than suddenly hearing crying kids & monotone 'walkthrough guides' blaring through your speakers just for being within proximity of another player.

Stealing in my experience is absolutely not worth it. Questing (and crafting) is where the money is. Most things you pick up, whether looting or stealing, is worth nothing unless you use it as an ingredient to craft something else.
