"traditional" RPGs. They're all more or less western RPGs, but not all western RPGs fall under "traditional". The trail starts at Baldur's Gate and Fallout, and includes pretty much everything with an isometric view option, castle walls made out of dialogue, and occasionally D&D rulesets.
Off the top of my head, Baldur's Gate 1 & 2, Icewind Dale 1 & maybe 2(never played it), Fallout 1 & 2, Neverwinter Nights 1 & 2, TES: Morrowind(oddball of the group), Dragon Age: Origins.
Not really saying they're all bad, but at best they will be timewasters for me, nothing more.
