Matewis: Oh Planescape Torment is pretty incredible. The writing and especially music is phenomenal. However the gameplay is very much still the same, for better or worse :P
About the gameplay, some months ago I recall reading someone complaining about Icewind Dale 2 how it constantly has battles which require lots of attention, planning etc. To me however, that is exactly what makes these RPGs interesting, the difficult fights which require some planning like which spells to use, how to approach the fights (like whether use lots of summoned creatures or area damage spells etc.).
I guess to me these RPGs are a bit like RTS games, tactical combat simulations. I don't care as much about the story or lack there-of, even if I did enjoy the story and characters in e.g. Baldur's Gate 2.
Matewis: But if you're taking suggestions, how about Wasteland 2:DC if you haven't played Fallout 1 and 2 yet (I seem to recall you playing Fallout tactics at some point?)
I've finished Fallout 1-2 and Tactics(modded version) and was planning to proceed to Fallout 3 & New Vegas at some point.
Other RPG series that I am supposed to go through is Gothic/Risen/Arcania/ELEX. So far I've finished only the first Gothic game, I enjoyed it overall. I just bought ELEX a couple of days ago. :)
Elder Scrolls is on a limbo for me. Finished Arena, I got stuck in Daggerfall (those damn mazy dungeons) and not sure whether to try to continue it or abandon it and proceed to Morrowind etc. Not sure if I'd end up with similar issues with the later games. Then again, as I don't have Skyrim yet, proceeding with that series is not high priority at the moment as my series is incomplete anyway (ie. I'd have to stop at Oblivion anyway).
Thanks for the tip for NWN. When starting a new RPG, I usually check some FAQ to make sure I don't make any grave mistakes in character creation and development, like how in e.g. Gothic 1 concentrating on archery is a bad idea (while apparently in later games it is a viable route).
