A few days ago, I tried out two older free and open-source (or "FOSS" for short) games. The first of which was Trigger Rally. The handling of the cars seemed a good bit out of whack. It still wasn't bad a rally racer. One certainly can design a course for this game. Though for me, I don't seem overly impressed with Trigger Rally (I don't hate it).
The other free and open-source game I played was Stunt Rally. Stunt Rally attempts to have you compete in a number of different mostly off-road circuits all with some fine graphics. I am in no way adept in taking on these courses. It's pretty hard, but I can surely see the entertainment value in taking on these courses. You have a variety of vehicles to choose from ranging from cars, trucks, a few motorcycles, and even some spaceships! I don't think I can take on any of the insane pipe style tracks that were created, so I'll stay with the more sane on and off road courses.
I'll compile three games into one paragraph, so here goes. I finally had a chance to try out the Cube series. The Cube games are a free and open-source series of mostly first-person shooters. Cube is often seen as a first-person shooter in the spirit of Quake and Quake 2. It is pretty fun from I played. It has nice graphics even as a mid-2000s game. Assault Cube can kind of be thought of as Quake meets Counter Strike. It is a spinoff that is multiplayer only. It's pretty cool if you're doing multiplayer with this game against bots or against real players. Don't expect the insanity of Unreal Tournament or anything with this deal, though. The final highlighted game is Cube 2 Sauerbraten. Cube 2 has a lovely graphics engine with some fine effects even for a mid-2000s type game. This game has been overhauled from the first series and remains fun to play. Basically play Cube 2 (or even the first Cube) if you like first-person shooter style like Quake or Quake 2.
And there you go. Make that five different free and open-source games I tried out recently.
