Yes that's why I accepted stylus based oddities in the first place, they're a bulk of the best games on the DS. But it's still technically not a genre, so I think mech games are fine to include. And like I said I've been very open to the genres brought forward cause I can't hate on the DS; Kart Racing could easily fall under Racing despite me not allowing the PSP to have arcade racers and Sim Racers as individual genres when they clearly are very different. But I allowed Kart Racers anyway even though there's literally only 2 games to consider. And I could have separated fighting games into 3 genres but that's a bit more debatable.You just used stylus based oddity as a catch all for a great variety of super creative games. If vehicular car combat is a genre worth discussing here, then this category that holds some of the best games of its era sure is. If you remove the stylus from the name, the PSP does have a small number of games in this category, for instance the two LocoRoco games.
That other poster asked if I was legitimately high though, that's what set me off. I may be many things but I have never been legitimately high. It's always been illegal :( . For legal reasons I will add 'if and when this ever happened'.
Edit: Vehicular Combat is absolutely a genre. Mech games are not but I think it's fine to keep them as one since stylus based oddities are there.
