Yes, there are good games that are just totally free. I've enjoyed the hell out of both ΔV: Rings of Saturn and South Scrimshaw lately. Both offer things you can purchase, but you get the full experience without them.

F2P with microtransactions isn't inherently bad. Legends of Runeterra is that way and is maybe the best-done F2P model I've ever seen.

I know Holocure isn't, but my gut reaction to F2P is to steer clear.

I wouldn't put Path of Exile in that bucket. The cosmetics and stash upgrades are there but they don't push at all.

True, but there is nothing wrong with that really unless it's a multiplayer game where you get unfair advantages. It's hard to expect a f2p game to not have micro transactions.

I have like 1000 hours in Warframe and only spent like 20$ on it. Even that wasn't really necessarily. You can farm shit and easily make enough of the in game money for what you need selling it to other players.
