Swords and Sorcery did an exceptional job bringing the video game to PnP.
Xenh - A lot of what you point out was indicitive of the original EQ video game (back when there was only 0-2 expansions). The genre went down hill with WoW dumbing the genre and status quo down. EQ eventually followed with its expansions.
Other genius things found in EQ was the mixture of mobs so that you couldn't say that a zone was STRICTLY for lvls 1-3. There were some lvl 5-7s roming the area that would take you out if you wern't careful. Also there was the intermingling of the factions. If you ducked into the wrong house in a town you were suddenly in the necromancer's guild and they all just decimated you for being a paladin.
Drejk - the spell lists mimiced the EQ video game almost exactly. The video game was based on mostly fighting and very little non-combat activities.
The biggest issues we had with it when we played was at higher levels. DR was through the roof to compensate for the high damage output which crippled most mid-low damage classes. Also the bestary gave great templates to make high level monsters, but gave no pregenerated ones - the DM had to create almost every monster in his campaign from scratch with the templates.
