Should I complete all side quests before chapter 4?
I heard that once going into chapter 4... you cannot complete side quests since you cannot go back into Athkatla until the end game. So because of this.... this is kinda bad since I haven't even recruited most NPCs in the game and I would like to set my party up for the Irenicus fights that does occur (I heard like 2 of them happen or some crap.)
I have a save at like chapter 3 but it won't make much sense overall so I'm guessing that chapter 2 was really meant for the PC and his/her party to stock up for the main quest (which is actually very good in terms of role playing BG2.) Normally I switch off between main quests and side quests so I wasn't used to these changes really. So should I just complete every little thing I have to do (side quests, NPC side quests and etc.) or will it be safe to go play some of the main story or does the game force you to play the story from chapter 4 to the end?
Also one other thing... I feel like BG2's doesn't have as much content as BG1... I mean in BG1 I was swamped with side quests and it took me a while too with the exploration, unlike BG2 where I feel they toned down on the side quests (I think BG2 as somewhere around 25 side quests whereas BG1 had 44 side quests)
