Up later than I should be play testing most of these. A few didn't show up in my FE, meaning that I'm missing some needed files.
I'll get those sorted in the next few days.
Planning to drop these, unless other people have a high opinion of them:
Backfire! - have enough games like this. This is the weakest one IMO
Final Blow - I thought the controls and gameplay were crappy
Hat Trick - It doesn't do much for me. Keep it because it's a classic?
Jitsuryoku!! Pro Yakyuu - Seems like a great baseball game without an english version. somehow I got into a menu to change my lineup or something and everything was in Japanese. Seems like this would cripple the game for people who don't read Japanese.
Pleasure Goal - one of the weaker soccer games on the list?
Soccer Brawl - Seems to be a rehashed version of one of the other snk soccer games. What's weird is that I enjoyed the other one.
This one has a power meter added. I can play the non-combat one fine, but can't get the hang of this one. Just me?
Slap Shot - controls and gameplay just aren't clicking for me. puck ends up going back and forth horizontally between the boards a lot.
Is it just me?
Other games I want opinions on:
Success Joe - I want this type of boxing gameplay in the list, but I feel like I'm just button mashing and there is no timing or visual cues to create the gameplay. What you say?
World Darts - bit of a weird game. It's like you're trying to control a drunken hand with the joystick. The countdown timer is your total time to take all 3 shots. I want to like it, but wish the drunken hand was a bit easier to control. I could get a single trip 20 each round, but it feels random to be able to get the hand in the correct vicinity. Give it a try and report back.

Winter Heat - can't tell if it's any good because my PC is too slow. I thought I'd be able to play in slow motion, but I have no idea how I'm supposed to be controlling the skier from the weird angles. My guy just falls over.
Billiard Academy Real Break is probably the best of the overhead pool games with a focus more on fun rather than overly serious, although if you're trying to keep the list 100% clean might be a little over sexualized,
It's got the exact gameplay I'd like to have, but being able to pan and zoom on the pictures of the women in lingerie is a bit much.
I'll add it to my own list, but comment it out on the batch file I make for this list.
People can add it if they want.
EDIT: Oh and Paigeoliver is correct about all the WWF games being horrible, but they stay because people will want them for the sake of nostalgia.
Choosing Sgt Slaughter was fun. A few minutes into the game, the nostalgia wears off.
