I just read a post at The Grand Tapestry, linking to this. That is one seriously interesting take on Types in T&T! When gaining a level you can "shift tracks" within a type. In old D&D and T&T there's fairly few classes, but they contain a lot. A fighter can be both a "paladin" and a "barbarian", basically they are the same class but different takes on the Fighting Man. Now, imagine that to be spelled out that way, and levelling up means broadening your scope as a Fighter?
Personally I think this ties in quite nicely with this post and others by The Fighter, eh... Paladin I mean.
Are you getting better at killing things, is that what experience means? The Old Way shows us the path of flexibility. Me like.
I might be zeroed out by gaming hiatus and an autumn cold, but some guys write some really good posts out there!
