One of the cheapest and funnest games for the price (it's also the cheapest solo game I got) was Terminator Dark Fate on Amazon. Normally it costs $7.95. Sometimes it goes on sale , so it can be even cheaper! https://www.amazon.com/ALC-Studio-Terminator-Dark-Fate/dp/B07ZBTWHLD/

The game is fun, with good replayability. Totally worth it's price.
