Genesis/Megadrive: up to 65% market share, beating Nintendo 4 holiday season in a row in the US, 40+ million consoles sold in the 90s. Before this console, Nintendo had allost 95% market share
That is a nice "mirage" to have.
And no, stop with that "Xbox was DC2" nonsense, they just bought exclusivity deals for games that were supposed to releaseh on the DC, that is all (Nintendo and Sony did the same btw - look at Sonic, Ecco, Eternal Arcadia etc..)
And yes, I loved the OG Xbox, mainly for these Sega games, so it is not me hating on it.
And to go back on topic, I would love a new Sega hardware, but it is never going to happen.
