I've played it for quite a while and I can assure you that you will only have fun if you play with friends, or, make friends in game and join an outfit/clan to play with. You'll probably also need patience and persistence as you WILL die a lot. Working together with all team mates is the most important thing and is very rewarding when done correctly.
Overall gameplay experience is really thrilling and fast-paced. IMO PlanetSide really captures the idea of large scale sci-fi warfare well. They did a really good job with the landscape/environment/weather/day and night cycle for a dynamic battlefield fit for infantry, vehicle and aerial fights.

Bottom line: IMO it's only worth the huge download (and the relatively large patches) if you have people to play with.

Becuase im not sure if ill actually like the game. 10gbs of downloading I wanna have some type of input on it.
And there are many FPS game out atm.

its f*cking free to play why would you "debate" on whether to try it out or not
