I stopped playing bw1 for about a year now and at the time I was maxed out, now I'm level 139, and heading for 150. Is 150 it or will it still be updated with new quests and things? I'm just seeing less and less activity here, getting less and less help with energy and I've been able to buy all the cheese bread I want with no competition. Just curious, I'll finish it but just wanted to know if it was it.

Yes Level 150 at xp of about 9,089,200 is the current Max, and there had been mention of new content but that mention was somewhere around Halloween and I guess it's never going to happen.
I play perhaps every other day. Don't even bother with the daily loyalty, and never even check with Sasha to see if anyone needs help. Almost all my friends are level 150 so I guess most don't play either.
The events had been updated but no new Event stuff has become available since the Schools Out event of around last June while I was hospitalized so that's about the only thing I'm aiming to play, and of course trying to win my first Diamond. The non-event stuff of the past year has been the area near Twiggy Lake, and the mini-map of Twiggy Lake and an update of the Kings Quests giving 8 squares all around the world.

I started playing bw2 right when it first came out but wasn't impressed either that's why I stopped playing it all together, glad to be playing it now, and leveling up pretty quick too, 48!!! in like 38ish days. I hope they somehow link bw1 with bw2, would seem to make more sense that way
