Options/suggestions:
Pinball:
1 - Alien Crush (seems better than Crue Ball);
2 - skip this genre (usually very long games! Or why not limit pinball games, like 1 hour or 1,5 hours maximum? Is it possible?);
3 - Crue Ball.
Sports:
1 - skip this genre (usually sports games have many random factors, or possibility to find easy patterns to repeat at get many "scores" in many games. Console sports games usually are very long games);
2 - Battle Flip Shot (Arcade);
3 - California Games (Genesis) (modes? all? scores?).
Run'N Jump:
1 - Magical Crystals (Arcade);
2 - Kid Chameleon (Genesis);
3 - Chiki Chiki Boys (Arcade).
Beat'em Ups:
1 - Battletoads (NES? Genesis?) (if ok, for speedrun);
2 - many Konami or Capcom games;
3 - Undercover Cops (Arcade).
Adventure:
1 - Flashback (Genesis) (don't know if the scoresystem is good).
Golden Era:
1 - I, Robot (Arcade) (don't allow warps);
2 - Ripoff (Arcade);
3 - Speed Coin (Arcade);
4 - Anteater (Arcade);
5 - Pole Position II (Arcade) (1st track)
6 - Zektor (Arcade);
7 - Robotron (Arcade).
Racing:
1 - Power Drift (Arcade);
2 - Pole Position II (Arcade) (1st track... It's for permafrostrick

);
3 - Super Off Road (Arcade? MasterSystem?) (loops limit? 2 loops?).
Speedruns:
1 - Pitfall (Atari2600);
2 - Aero Fighters (SNES) (Time Attack, secret mode accessed by code);
3 - Adventure (Atari2600);
4 - Pitfall II (Arcade);
5 - Battletoads (NES? Genesis?) (if ok);
6 - The Lion King (Genesis? SNES?);
7 - Ghost'n Goblins (Arcade) (1 loop? 2 loops?).
Shmups w/ short time:
1 - Aero Fighters (SNES) (Time Attack, secret mode accessed by code);
Falling Blocks:
1 - Super Puzzle Fighter II Turbo (Arcade);
These seems ok:
Paddle (Break Out) = Gunbarich - Arcade/Coin-Op
Fixed Shooter (Galaga) = Cosmo Gang the Video - Arcade/Coin-Op
Vs. Fighter (Street Fighter) = Double Dragon: Neo Geo - Arcade/Coin-Op
I'd avoid:
- Games that are Language dependent, like many RPGs and Quiz And Dragons.
- Long games;
- Lucky factor games.
