The TF2 example is especially. Seems a better solution, when facing the issue of updates leading to a worse experience to lower spec machines, would be to iterate and make TF3 or keep a classic TF2 (like they did for counter strike). User base with low spec machines must not be with it, though, and people may have upgraded hardware over time. There's also the slew of new video games that complete for user attention/money. Tons of factors to think about!
