Guilty pleasure? Not at all! Just pleasure :)
As for whether they are "super-detailed" toys, it depends whether one thinks sport cars are "super-fast" toys, and MP3 players are "super-convenent music toys". In essence, most hobbies we do simply for the pleasure of it. These are the things we like to play with, so if you want to define toys as such, so be it. I mean, if you like to play softball on the weekends, what really is the difference?
As to what motiviates me, both the history behind the subjects I model and the artistic skills needed to assemble, detail, and paint them.
Welcome back to modelling!
