Rollergames were made in 4x bigger number than Radical! Radical! was rare even then.
The bad thing about Radical! is that it looks and sound a lot like TPZ or Dr. Dude so it is instant turn of for people that doesn't like those two even if they never played it. But it plays differently although it's all about ramps.
Sure, but lawyers rule the world and all that. It's like how TV sitcoms have been using the same dummy newspaper for two decades now, or product packaging sometimes is blacked out. Also, I believe Orange Slice is no longer made (RIP). I thought those team names belonged to an official league, so those are also trademarked. It would probably be a bit complicated to do Rollergames.why? It's more like a free commercial for them than anything else. It's not that someone would pay 5$ just to watch pepsi logo.
The same goes for those brands in Blackwater 100.
