Rogue = my favorite class in nearly any game. NWN more than any others.
Sneak attack 10d6 + DC 14 Stunning mace + DC 14 sleep mace = pretty close to the best attack ever.
My girlfriend plays a dual katana wielding Weapon Master. Hot.
Something I forgot about for RPGs. A while ago, I really enjoyed the
Exile games, particularly
Exile II: Crystal Souls, by
Spiderweb Software.
The graphics are, obviously, dated and sub-par, but this is an entirely independent company, here, consisting of three people, so it's understandable.
Exile plays similar to Icewind Dale II, in that you play up to 6 characters, and each character levels similarly to a DND character (specific skills for each weapon, armor, skill, etc. with racial bonuses/penalties affecting leveling time). The worlds are e-NORMOUS, and there are hundreds of side quests (possibly even thousands... like I ever finished). The gameplay is pretty fun, revolving mostly around the combat strategy and character development.
On their website, you can download large demos of all of their games. The demo of Exlie II alone would take you probably 30 hours to finish
entirely, or just a few to run through it... depending on how you play. I highly recommend any of them, but as I said before, I enjoyed Exile II the best.
The other games they have don't play as smoothly or enjoyably, in my opinion, but they're at least worth a look.
