What is a game you liked, but were disappointed to find it didn't have sequels, or the sequels went in a different directions, etc.?
Basically a game that you would like to see more of, but there just isn't more?
Post your game and people can respond with recommendations of similar games (similar gameplay, similar ideas, similar vibe, etc.)
For an example, let's talk about
Gyromite for NES. Obviously the "right" way to play was using Rob, but I think most of us just played with a second player or fumbling with two controllers.
So what is the essence of Gyromite? Distilled down you can look at a few things.
In the main game mode, the object of each level is to navigate the levels and collect all the bombs before time runs out. So, functionally similar to maze games like Pac-Man
However, there are also pathways you can take that will get you stuck, so there's a puzzle element there as well. So maybe actually closer to something like Lode Runner. That seems like a decent match...
...At least if it weren't for the moving steel pylons in Gyromite that change things up significantly. Those are helpful to raise/lower to get around the stage, but also can be dangerous since you can be squished by them as well, giving a bit of Elevator Action vibes (though that game is very different)
Let's leave that train of thought for now and go to the other main mechanism - One person plays the main role while the second player manipulates the environment.
Certainly there are a number of co-op games where each person in turn has to assist the other player in making progress. Games like The Adventures of Cookie & Cream come to mind. Probably a better match would be the Murfy levels from Rayman Legends on the touchscreen systems where one player as Murfy manipulates platforms, enemies, and other obstacles.on the touch screen while the other player(s) try to navigate through it.
Actually I think that is pretty close to a match to the "collect all the things" mechanism too, if you are trying to find all the lums and Teensies.
So there's an answer. Rayman Legends (Murfy levels) = Gyromite 2.
Now you can pick a game (or even a specific part od a game) that you enjoyed, and others can make suggestions based on that game.
