Yeah, that Bukkuriman Daijikai "game" really isn't a game at all. It's probably just like that dinosaur encyclopedia game although I haven't seen the dinosaur game.
My cousin and I went though the entire Bikkuriman universe way back when. Neither of us knew any Japanese but we managed to answer all the questions in the quizzes. I'm surprised both of us had the patience to go all the way through.
As for the other games pictured earlier, I actually liked Tokimeki Memorial. I'm not a big fan of those dating sim type games, but there's a lot going for it. There's a _ton_ of speech... lip-synced too! Plus, there's a number of mini-games. Not too complicated but interesting. Supposedly there's a mini-shooting Gradius-like game in there somewhere, but I haven't been able to find it.
And finally, AFAIK, this is probably the first ever console dating sim game. Another PCE first.
Unfortunately, it was also the start of a billion other console dating sims.
