Throughout the 90s there were plenty of people trying to capitalize on the popularity of good 2D fighting games like Street Fighter 2 – Metal and Lace: Robofighters is one that tried to get an edge via the sex sells angle (A Californian actually invested a lot of work expanding the original production from Japan and giving it that charming back story).
Now, while it looks like this should be a porn game and the publishers did eventually import and localize some porn games – the default release of this was supposedly suitable for all ages (you had to pay for a patch/expansion disc if you wanted to see naughty bits).
Sadly, the fact that this game was all but forgotten and it seems not even the developers could take it seriously has not deterred modern day developers from thinking if they crank the sexy appeal up to 11 out of 10 they’ll rule the market.
