Good free games you play for a long time?

[Jernemies]

well you can find them on website and download them for free

And that, ladies and gentlemen, is what you should never say around here. There's even a rule about it... but yeah

About free games, let's start with

HF - You know it. If you don't, it's like LF2 HD not modable. By Marti, of course.

Soldat - Fast paced 2D sidescroller.

Xonotic - A fast paced FPS. I don't really know about this one, but it's just because of a bad comp.

and end with

Battle for wesnoth - A turn-based strategy game.
