Tome 4 (http://te4.org )is a really polished, modern take on roguelikes. It's also based on a pretty modular, GPL3 licensed engine, in case you ever feel like making your own.
Yeah, I played that quite a bit a few years back. Unfortunately at the time quite a bit of some of the runecaster class was broken, but it was still quite fun.
That was all before the current engine, which I have to say looks pretty awesome from videos and screenshots. I'll have to try playing it again.
If you're talking about the old Middle Earth one (tome2), then it's a very different game in many respects. A lot more changed besides the graphics, but it's turned into a pretty polished game that encapsulates many of the best parts of *band roguelikes.
