Nice selection you're selling here. I'm not buying (already own more than enough), but I've got a few recommendations for anyone else who is looking.
If that "Gambler" game is part of the Gambler Jikochuushinha series, then those games are usually pretty fun and worth the $2.
Benkei Gaiden has some really nice chip music, worth paying $2 to hear.
Gaiflame is a cool, early strategy game from the Langrisser team. Crest of Gaia to a lesser extent, since it's visibly older, but it's part of the same series.
On the other hand, Blodia is terrible... but playing it will bring you spiritually closer to Esteban, since he harbors inexplicable love for the game. So I guess that's a recommendation, kind of?
