Prices are per version and are not interchangeable, and neither are the reviews: conversions in this era were often built by a different studio than the original, so a score earned on one machine says nothing about how another plays.

The Sega Genesis version
A cheerful skateboarding-dinosaur platformer, priced above the middle among US carts and much dearer in Europe.
This is the Genesis version of Radical Rex, a platform game from Beam Software published by Activision. It came out in North America in 1994 and in Europe in November 1994. You guide a fire-breathing T. rex who skateboards through side-scrolling levels.
The Genesis game changes the villain: the antagonist is a weasel-like mammal called Skriitch rather than the Super NES game's Sethron. GamePro found the Genesis version had slightly less colorful graphics and more muffled sound effects than the Super NES one, and lacked the entertaining intro rap, but kept the essential elements that made the game fun.
What the press said at the time
“Rex looks extremely tired and lacks the injection of humour or originality that makes the likes of Earthworm Jim and Pitfall so innovative and playable.”
How the Sega Genesis version differs
The Genesis and Sega CD versions replace the boss Sethron with a weasel-like villain named Skriitch, who behaves the same.
GamePro found the Genesis version slightly less colorful, with more muffled sound effects and no intro rap, though it kept the essentials that made the game fun.

Before you buy
Among US carts it sits above the median. The European cart usually costs far more than the US one, both loose and complete, so a US copy is the cheaper way in. It is a cheap-tier game with no per-game fake concerns. A complete US copy means the case, cartridge and manual.

The Sega CD version
A cheerful skateboarding-dinosaur platformer that reviewers felt did not need a CD.
Radical Rex came out on the Sega CD in North America in November 1994, developed by Beam Software and published by Activision. The Sega CD version has some new levels and enemies, but GamePro found the graphics and sound virtually identical to the SNES and Genesis games.
Electronic Gaming Monthly's reviewers were harder on it. One complained that this was another cartridge game thrown onto a disc, and the magazine felt only the CD soundtrack justified the format.

Worth knowing
- Level select. Game Informer's Secret Access column in September 1995 printed a stage-select code for the Sega CD and Genesis versions: on controller 2, press A, C, Down, Right, Up and then B at the title screen.
Before you buy
This is one of the pricier North American Sega CD releases, well above the middle, so it is worth a careful look. Ask for photos of the disc's printed side, its data side and the inner ring: the label should be printed on the disc itself, with moulded codes in the inner ring, and the title should match the case. The tall plastic case is fragile and is often swapped for one from a cheaper game, so check the case is the right one.
