I've been playing Far Cry 3: Blood Dragon. This is an expansion for Far Cry 3, but it's also a standalone product, and turns the original serious game (which was about killing people traffickers on a remote island) into a parody of an 80s action film, set on an island full of robot-zombie cassowaries and neon dinosaurs that shoot lasers from their eyes.
Michael Biehn of Aliens and Terminator fame voices "you" - Rex Colt, cyber-commando. (I actually think both of those films are really good and that Michael Biehn is a decent actor, and it's just bad luck that he's associated with 1980s kitsch). The whole macho 80s action movie joke is getting a bit tired, but this game is at least 10 years old, so it was one of the first to do it, and some of the dialogue is quite funny. There are some cut scenes that would look primitive on an Amiga 500, which adds to the charm.
Perhaps the best thing is that it's short and simple: the skill tree stuff from Far Cry 3 has been replaced, and you just get more powers by killing more stuff. It doesn't outstay its welcome and it's pretty good fun.
