Most people already know this but I'll jump back in as I learned this embarrassingly late. You can make your games much faster and tougher... tonight. When I first got my Whirlwind I was playing 30 minute games on it... and racking up around 50 million points. to be honest it kind of ... sucked. But it's my favorite game now. In order to make it my favorite I opened up the outlanes, increased the pitch, rebuilt the flippers, and switched out the rubbers. Now I play 5 minute games and am lucky to get 10 million points. It's awesome.
My main recommendation on getting a game that plays well in a shorter amount of time is to find a game that doesn't require a ton of steps to rack up the big points. ST:TNG requires you to complete 8 modes to get wizard mode (which I've never gotten). You have to work hard to set up and get those big points. Whirlwind isn't like that...
Other games that fit the not alot of setup to have a good game include the early Pat Lawlors like Earthshaker, Whirlwind, and Funhouse, some of the earlier Steve Ritchie's like FirePower, Gettaway (I've never played it), and High Speed. If you want a more modern game look into "Munsters".
No matter what you end up with... it will be pinball and it will be fun.
It's on the other side of DC, but if you've never been there check out the High Speed, F-14, Firepower, Munsters, and Taxi at Mom's Organic Market in College Park https://pinside.com/pinball/map/where-to-play/11547-mom-s-organic-market-college-park-md... They've got like 40 games.
