BG2? Kill those slavers. Kill those evil druids. Get that item back from X. Gather 15 000 gold before you can begin the main quest. Clear this castle of trolls. That game didn't have a whole lot of quests that went beyond ''go kill these guys because evil''. It still probably has more hefty content than Inquisition, but it's far from being leaps and bounds ahead.
Methinks nostalgia makes some people have a bit of a selective memory sometimes.
I am sorry but this so blatantly misrepresentative of the content in BG2 that you have forced me to break the facade, not sure if you are trolling or so hardcore a Bioware fanboy that you need to blatantly misrepresent content that was done well in the past in order to make Inquisition's content look more acceptable and less **** than it actually is.
The mere fact that you are trying to compare the de'arnise keep to the base level fetch and "kill X amount of Y" quests in Inquisition shows how desperately you are grasping at straws, the quest was more than merely "go here, kill trolls" there were secret passages to find, hostages to rescue, the quest had story and character and one of the best weapons in the game hidden in 3 parts of the keep, it felt urgent and felt like you had a reason for doing it, it was probably comparable to the best main quests in Inquisition (if not better) and it wasn't even the best quest in the game.
Every thing you have said "Kill those slavers", "Kill those evil druids" ect are all gross simplifications of much deeper and involved quests, "kill those evil druids" is not merely killing evil druids, it starts out by having you investigate the wild animal attacks on Trademeet in which you find end up finding out that the local druid grove has been inflitrated by shadow druids who have convinced the grove to attack the town of Trademeet, the quest ends with you challenging the leader of the grove with a druid of your own for leadership of the grove. Kill those slavers isnt merely kill those slavers, it is a quest where you through your digging expose the seedy underbelly of the Copper Coronet and the seedy entertainment that goes on behind it's closed doors, freeing the slaves there will expose a slave ring that goes much deeper and they will ask you to finish it once and for all sending you through the sewers (where along the way you encounter a series of riddles that will unlock a talking sword) and through a secret tunnel where you find the slaver's headquarters and end the opperation for good, all these quests have story and character and more than merely killing a bunch of dudes on your way down a checklist, the Quest design in BG2 is miles ahead of that found in Inquisition and it has nothing to do with nostalgia and selective memory.
