Best free-to-play games on Steam right now?

Depends what you're after - *Counter-Strike 2*, *Dota 2*, and *Team Fortress 2* are solid multiplayer standbys, while *Warframe* and *Lost Ark* scratch different itches if you want something with progression. If you want something less competitive, *Tchia* and *Baldur's Gate 3* technically have free trials, but honestly your best bet is filtering Steam's F2P section by recent reviews and playtime to see what's actually holding people's attention right now.

If you want something with actual narrative meat, *Honkai: Star Rail* and *Genshin Impact* are free and genuinely polished - way less grindy than people assume if you're just chasing story. The earlier answer's solid on the multiplayer classics, but those two lean into single-player adventure instead, which scratches a totally different itch if you're burned out on competitive stuff or team coordination.
