Valve says Marathon is Steam Next Fest’s biggest demo… and everyone argues

Valve highlighted Marathon’s Server Slam as the most-played Next Fest “demo,” which sparked debate because it’s basically a big beta/stress test.

What it means for gamers: the event gets more attention (good), but smaller devs get less oxygen (not great). For players: it’s still a win—more good demos, more free try-before-you-buy.

The controversy centers on whether "server slams" and "open betas" should be categorized alongside traditional demos, potentially skewing metrics for indie developers.
