Dragon Age is another example--no online multiplayer (ala one of its predecessors, Neverwinter Nights), no custom content.
I have a feeling I have made this exact same reply to you before, but Dragon Age is a successor to BG1/BG2 not NWN. The emphasis is on heavily scripted dialogue and plot w/ cutscenes, environments are manually designed for each area, and companion characters and dialogue is a major focus.
NWN was fundamentally about the toolset developed for it and the module based content was friendly for user development at the expense of many of those earlier areas of emphasis. The plot was still reasonably good but it felt like playing a D&D game with a bunch of interchangeable set pieces and monsters (not a bad thing). Online was a necessity for that format.
Recognizing that we exist in a world with scarcity, the addition of multiplayer to DA and ME1/ME2 would both have made them significantly weaker singleplayer games. I enjoyed both of them more for being successors to BG/KOTOR respectively then I would have enjoyed a NWN3.
I don't see why there's all of this hate for MW2. I played CoD 4 once and hated it, I played CoD World War once and hated it, but I really enjoy the hell out of MW2. It's a fun tactical shooter.
Apparently we're all fed up with company_name1 because they have
the nerve to sell product_title1 for product_price1, when obviously it should be product_price2. Things have gotten so heated that some posters have even hinted that company_name1 may only be selling product_title1
to earn a profit!
