BG 1, first wolf encountered could 1 shot MC. Worse, every kobold with the bow could one-shot MC with lucky crit.
- BG 2 - every mage could suddenly one-spell kill MC on failed save. Liches in tavern back-rooms too.
- World of Xeen, MM 7, MM 9 - stepping into the wrong dungeon or even opening the wrong chest could obliterate whole party in the second.
Xeen allows full party creation from the start and free roam. The first dungeon (Dwarf mines) is piss-easy and loads you up with enough treasure to practically finish Clouds by yourself. Not to mention you can always visit Dark Side and get zillions of XP for nothing and break the game if you feel like it. The hyper challenge of later dungeons is a scaling problem; the rest of the game is so easy the only way it can challenge you at all at level 200+ is with full party wipes.
The hardest part of BG 1 was the walk across two screens to get Jaheira and Khalid, and the Skeleton Warriors in the final dungeon. Nothing else remotely approaches the munchkinized opponents of Kingmaker. The Baldur's Gate games actually followed the Monster Manual very closely.
Baldur's gate 2 starts you off with a very effective party. Solid fighter, mage, druid, and rogue who can spot every trap and unlock every door. Game is free-roam after the starter dungeon, if you get stuck you can go someplace else, you are never forced along a determined path again until *well* into the game. Nothing major has a time limit. Certain quests lock you into areas (Planar Sphere) but these are all optional and can be approached once you've prepared yourself without any time limit. Both games allow full party creation without limits. They also have a very effective and well-rounded cast of recruitable characters, unlike Kingmaker's extremely limited cast of gimmicky specialists.
Very bad comparisons, the Baldur's gate and Might and Magic games are leagues easier. Again, this is a circular argument:
"Old D&D games were just as hard."
No they were not, they didn't have time limits and they allowed free roam
"Who cares, I like that Kingmaker is harder."
Pick one argument and stick to it, stop revising history just to try to support your point.
