I saw this disc for the first time in sega-dc.de a long time ago But it has not been until now that I've been able to get it for my own collection. My copy has an insert that gives you £ 5 discount on the purchase of Re-Volt when it releases, and it has the 'Electronics Boutique' (EB Games) logo on it, so I assume this demo was a UK thing, maybe exclusive to that store. My question now is: does anyone know the real story behind it?
