Baldur's Gate/Baldur's Gate 2
Neverwinter Nights
I did not like these games at all. Perhaps it's AD&D's difficulty of combat -- you have to rest after almost every fight, especially if you're a magic user (I HATE the way AD&D rules treat magic), and the level of micromanagement is ridiculous, particularly in BG. Perhaps it's the sparseness of loot, especially in NWN -- I never feel rewarded for what I accomplish. Or perhaps it's the fact that I was promised some real moral choices to make in the story line, and was let down -- almost every dialogue contains a "good" and an "evil" path, and these are always pretty obvious.
In BG, I was annoyed by the fact that I could not play at my own pace and accomplish objectives on my own timetable. I was constantly hounded by party characters to go and solve "their" quests, to the point where they would leave my party and take my gear with them! I am someone who likes to complete as many quests as possible, and this was not feasible in BG.
In NWN, there is also the issue of the FUCKING HORRIBLE henchman AI. If you have a magic user for a henchman, he/she always burns his/her spells on easy monsters for no reason. If you want to use magic properly, you have to play a magic user, and take a fighting character for your henchman.
For modern RPGs, I much prefer the likes of The Witcher. It uses the same engine as NWN, but the plot is much more engrossing, the world is a darker/grittier/more inhospitable place, and the action is not broken up by the constant need to rest and re-acquire spells. The moral choices you make are actually difficult and require thought (often forcing you to wrestle with two equally "evil" courses of action). Combat is largely action-based instead of strategy-based, but there is still strategy involved. The level of micromanagement is whatever you decide it is -- you can choose to be extremely involved with the item-crafting and ingredient-harvesting system, or you can just fight your way through the game, buying whatever you need along the way from merchants.
