NWN: ahem, me too. As in I'm still slogging through the OC, about 1/2 way through the 2nd chapter if I guess correctly. It's linear, can be tedious, but I sort of like the combat. Hireling mostly does ok and stays out of the way, and my summoned pet does it's summoned pet thing which is pretty limited. (Playing dwarven cleric.)
My problem is that I regularly stop playing for weeks or months at a time, then have to re-learn the weird circle interface, re-check spells, feats, quests, journal, etc. But I've really found that I like this particular Bioware game much more so than I did their Infinity Engine games. The worst part is that I'm not really sure why...
Lemme see, also picked up KotOR this summer. Played about 5-8h or so, nothing really spectacular here yet... then again I'm not even remotely a Star Wars fanboy, so that may be part of the problem, although I do enjoy scifi and the odd space opera...
Oblivion. Agree with the others and independently arrived at the conclusion that the game was little more than graphics with a lousy attempt at a game attached to it one day while staring at a window asking myself: WTH why can't I enter through a window? climb a wall? then hear some NPC utter: "I saw a mud crab the other..."
EXIT. (It's worth getting to take a look at for a discount, e.g. Compuseless had it for $30 the other week...)
Dungeon Siege II: mindless Diablo 3D wannabe. Even though I only paid $20 for it, I still feel ripped off.
Dungeon Lords Collectors Edition: Heh. I never had the original and feel sorry for the people who bought the original and the bastards at Dreamcatcher for not releasing a v1.5 patch, but I sort of like this one even though I usually just abhor action "RPG"s by default.
PoR: too bad. I FONDLY remember the SSI gold box PoR. I still think it was one of SSI's best gold box AD&D games, and IMO the best of the PoR gold box series. I also like the Treasure of the Savage Frontier series. Then again I had an unnatural attraction to SSI RPGs back then, esp. Wizard's Crown & Eternal Dagger.
X2 & X3: While not RPGs are pretty decent open ended space sims if you ignore the fact that the combat is pretty lousy.
Wizardry 8: If you missed that one too, and can find it at a decent price(good luck) is worth picking up, especially if you like turn based combat set in a first person, most free roaming based world. Combat can tend to take quite a bit of time to resolve at the later levels though... and no you can't have and/or borrow my sacred copy(or even look at it...)
Gothic 2 Gold is decent, and reasonably priced.
Gothic 3. I'd wait for some more patches, and maybe a price drop or 2.
Mage Knight: Apocalypse: I believe that txa1265 may have some commentary on that one... review?
Dark Messiah: Isn't that basically a FPS mostly using melee weapons?
(In that case I'm eagerly awaiting Half Life Episode 2, most importantly, with Team Fortress 2 as I still regularly play TFC...)
