Arcanum was a hardcore computer role playing game, not some dumb first person shooter.
Strawman. Nobody talked about any first-person shooter here. But if you want to talk about "hardcore computer role playing games":
Baldur's Gate 1 manual - 51 pages. 1998.
Baldur's Gate 2 manual - 266 pages (~150 pages is a list of spells, by the way). 2000.
Fallout 1 manual - 121 pages. 1997.
Fallout 2 manual - 166 pages. 1998.
Morrowind manual - 52 pages. 2002.
Icewind Dale 1 manual - 161 pages (~50 pages of spell lists). 2000.
Icewind Dale 2 manual - 152 pages (~50 pages of spell lists). 2002.
Vampire the Masquerade: Bloodlines manual - 64 pages. 2004.
You don't need to read manuals for D&D or D&D-derived games if you're already familiar with the system. Anyone new to D&D had to read the manual for Baldur's Gate (or any first D&D game they play).
I was playing games without reading the manual first since DOS games. I was new to DnD and didn't read the manual to play Baldur's Gate (or Icewind Dale. Or Fallout, etc.). I read it later for the little bits of lore it had (which was nicely done in-character).
So I think I had a plenty of experience in "hardcore computer role playing games" before coming to Arcanum, and still I needed to do some digging to make a character that was decently-enough combat-oriented to deal with the wolves (same thing for Fallout 2, by the way). Because you can't really gauge what stats are "good enough" without some actual testing. Somehow I didn't have this problem in literally ANY other cRPG I played before and I played ALL of them.
