Héhé, the game "IS" ... chuchu rocket.
It wasn't meant to be a ripoff but more an anachronic release.
There are millions of true ripoff around (ie : game concept refurbished under a totally different skin), but I dont think its really the case here, obviously.
I dont know if much people bought this game, nor played it, I suspect less than I have fingers on my hands. But well, its supposed to be as close as possible as what Sega could have done if they wanted/accepted to.
It wasn't exactly meant to be sold. It's CDR (afaik) and I'm not entirely sure but the copy protection is probably indeed ironic.
It would be interesting to have feedback from people who have a copy btw.
Take care
