it's a pleasure to be taken into account <3 unfortunately I have many limitations due to my computer and I completely discard any online game :c but if you ask me about any idea I would recommend a complicated game in which we must meet certain requirements (either score, time or just see who gets further) and I have in mind one:

there is a game called Shingeki no kyojin Tribute game (yes, it is based on the anime), created by feng li , which has a very difficult gameplay to master because of its somewhat complex controls, but it is not impossible and has many modes, one of them is waves, could be the one who manages to get further , also has an online mode that lends itself to many other competitions such as a tournament in waves based on the person who kills more titans or who wins the last to survive as it is a game that you must have a lot of skill and good reflexes also in a single game can participate 99 players at the same time, is not a game of the most popular but if I say that it is very good.
