Games should not be locked to any resolution any more. There is no reason for them to be. Back when 800x600, 640x480 or even 320x240 resolutions were expected, raster graphics were an acceptable requirement for any game aiming to have reasonable rendering speeds.
Now, however, graphics have advanced to the point that vector graphics can be done completely smoothly in 2D just as they are in 3D.
The only limiter at this point is the display, which definitely has a longer lifetime than the actual computer. I think it is a valid assumption that most (and by "most" I mean over 90%) of computers - even running casual games - will happily deal with SVGs.
SVGs give us more than compatibility, too. There are many technical gains there, including the ability to freely scale things without the destructive impact we see when scaling raster graphics.
I often use vector graphics as a reason why the games that come with the GNOME desktop environment are actually very impressive, even compared to those that come with Windows Vista. Vista's may be nicer looking at first glance, but if we ever get 12800x8000 resolution displays, they will be left in the dust while GNOME's look just like new. For accessibility, SVGs are a great thing since they let the player resize the game in windowed mode, completely intuitively. Granted, that ability is not immediate and not possible in all cases, but it is much easier with SVGs than with rasters.
