I do have a wife and a 22 month old son, he is so energetic it's hard to find the time to get away and play anything, usually when he sleeps for a nap during the middle of the day.
I tried to play Star Fighter but could not figure out the purpose of what I am supposedly doing and the controls! Definitely tho finding a game I can shop at for 30 minutes to an hour every couple of days and save the progress to eventually complete would be good. I absolutely loved Solar Eclipse for the Sega Saturn so I was happy to buy and try out Total Eclipse, I played maybe an hour's worth last week and got stuck on level 8. That game is challenging for sure as on some levels you have limited hits before you die and have to restart. I wish there was an invincibility code for that game (like there is for Solar Eclipse which was the only way I could beat it after giving up). I need to figure out the gameplay and controls for Star Control 2 as well so i can get further in that game and Star Fighter.
I agree on the American Lazer games, I love those, tho they are super finnicky when it comes to hit detection. I really enjoy Mazer but it isnt one that can be played, saved, and then picked back up. The only way to stop the game it to let the time run out on the "continue" clock and the game ends, otherwise its unlimited lives.
I started playing some Iron Angel of the Apocalypse and got 9 levels in and am a little stuck. But it allows you to save along the way and pick back up which is great. I think the ETA to finish form what I gathered online is almost 6 hours so I would likely feel accomplished if I complete it!
As for Soccer Kid, I played it on the Atari Jaguar and I couldnt get more than 2 levels in. But I did see there are different level codes posted online which could help get a bit further along.
