It's still unreasonable to suggest Linux as a mainstream gaming OS when more than half of the top ten per [1] (so, statistically, the games you likely want to play) are either totally unplayable or have moderate-to-severe problems, with precisely zero having a platinum (perfect) rating. This is changing, but we're not there yet. When Linux gamers can expect an experience on par with Windows, rather than a degraded one involving glitches and arcane tweaking, it'll be safe to recommend in good faith.
