[Unwise]

Actually, I think the comparison between Starcraft and Dom2 is fairly apt. The reason people are still playing Starcraft six years after its original release isn't because their are free multiplayer installs, it's because the game-play still hasn't been completely eclipsed by a comparable game.

Sure there have been a truckload of RTS games with better graphics and incremental innovations, but these are trivial at best and interfere with the game at worst.

People still play Starcraft because they can look past the dated graphics and see the superbly balanced game underneath. It helps, of course, that Starcraft was polished to a glossy sheen before release and the interface is still very intuitive.
