I guess this website doesnt list every PCE game ever made? http://www.thebrothersduomazov.com/
I can't find Dragon Ball Z there.
It only lists the games reviewed. Thus, it grows every month, but it is not an exhaustive list.
Personally, the best resource for looking stuff up is:
http://www.pcecp.com (STRENGTHS: (1) "COMPLETE" LIST OF TITLES, and (2) search with filters! I love it! I don't think it has been touched in years, but it is still great. Did I mention how powerful the Advanced Search is? It rules!)
http://www.pcengine.co.uk (STRENGTHS: tons of wonderful stuff, like videos, music, recommended games, Bucci's reviews.
Back on topic: Of course my daughter plays all the old-skool games. Yes, she plays Wii and iOS and PC games, too. But she totally appreciates old-skool arcade and console games.
However, I try to introduce games that I know will appeal to her (I don't want to poison her with clunkers, even though I love a lot of clunkers).
Puyo Puyo and
Buster Bros. on the TG-CD?
Hell yes we play them all the time! She's 8 years old.
Aero Blasters or
Monster Lair 2-player co-op? Way too difficult for her, and she quickly loses interest.
And, sadly, I am corrupting my daughter by listening to a lot of video game music.
Hopefully, she won't hate me.
