I've played up to early 20's with several different classes, problem
is that melees are frustrating to play alone and casters get killed
too much alone. Also, there are some doors you can't get through
without specific races / classes, so having a variety is good. About
the best you can do solo is play a thief up to mid-teens and then dupe
it and start dual- or triple-boxing. Thief gets Death Darts early
enough so it's liveable, and its health scales FAR better than
wizard's.
Personally, though, I prefer playing Sierraland games. Those are what
set TSN / INN apart, especially Red Baron, which I haven't been able
to find a really good multiplayer alternative to yet. As I've posted
before, if you want to set up a few games in Sierraland evenings or
weekends, give me a call at
(636) 825-2299 when you're available to
log in. It's the only efficient way for meeting online.
