there are 3 packs you can buy on steam for POE 2, if I just buy the early access at 44$ is that like the normal game and I have to buy the 150$ package later on for full game or it's only cosmetics?

The $44 will get you the full game, $150 is just cosmetics

tyvm for info!

You should be able to buy a working early access code here for your 1200fg. That is another option for you.

The game will be free bro

most people would rather get the shitty early builds/learning done before league start.

Game full release will be free to play
The packs are supporter packs will grant you with some cosmetic and often with some prenium currency wich can be used to buy more cosmetic or stuff like stash tabs
