Gtr — R34 Car Parking Multiplayer
Only download if you’re a casual R34 fan who enjoys parking sims and doesn’t expect a true multiplayer community. For the real experience, play the original Car Parking Multiplayer (by olzhass) and buy/trade for an R34 there – you’ll get better physics, active servers, and less bait-and-switch.

To the previous commentator’s question: Does Groovy on Grails change things?
Well, first of all there’s also JRuby that is built on the Java platform. So you can have Ruby and RoR on Java directly. Then Groovy and Grails are there and provide similar capabilities. That changes things… but not in the way many of the old Java fogies may have anticipated: It validates DHH’s point of view in the strongest way possible. Dynamic languages are a powerful tool in any programmer’s arsenal–if you get exclusively attached to Java [1] and ignore dynamic languages, then do so at your own peril.

[1] The idea of getting exclusively attached to a particular language/platform is silly–they are just tools. Kill your ego. Open your mind and explore new technologies and techniques so you can use them when appropriate.
