open it in Steam and add it to your library.

This is free to play. You can't add it to your library, from what I can see. When the button on the store page says "Free", you can add it to your library. When it says "Free to play", you can't.

Confirming after installing then uninstalling just now, if you uninstall it the game is removed from your library.... you can then play it again by going to the games store page and clicking on "play now" which will then install it again. Something interesting about free to play on Steam, a while back Evolve Stage 2 became free to play, I played it for a few days then uninstalled it, it was removed from my games list because it was just a free to play game, not free to keep, but then when Evolve Stage 2 shut down the dedicated servers and free to play version, the game was added to my games library, so now I have Evolve Stage 2 without purchasing it, I wonder if that was a mistake or intentional haha..

Probably due to the people who bought it. You can't have games you paid for be deleted from your library. It seems it wasn't worth the effort trying to distinguish between people who bought it and those you only got it after it went F2P, so they just added it to everyone's library.

I never heard of this, and apparently not many others have since it doesn't even have a listing on the Proton compatibility list. I guess when I come home this afternoon I'll be the first to post something on it. I'm not sure I understand why this is free to play instead of free. It doesn't seem there's any in-game buyable content.

I bought it as free to play and it installed fine, strange playing a game without texture but certainly interesting for a four year old game.

Looked interesting until seeing that its the same tedious environment throughout with little variation. Would imagine after 15-20 min of the same-same would want to uninstall. No wonder its free. [youtube=yvmfKPtQn1E]

Free is nice. Added.

I actually prefer this to Valves Portal, also the environment changes all the time and the detail in the background adds to the games atmosphere....oh and its free.

"NaissanceE will be available for free tomorrow the 21 of September" Posted on the 24th LOL. And it's F2p not "free" for a limited time. You can play this for free whenever you feel like. It seems the devs' first language is not English. Hence the confusion, as it sounds like he is saying it is free ON the 21st, not Free To Play FROM the 21st onward.
