Here isn't really the right place to advertise your game.

You can't just go into games you think are similar and advertise your runs. If there aren't people that are interested in the game that doesn't mean you can go anywhere else and try to get people to run it. If people would like to run it they would go the leader boards and look themselves. Advertising in other forums just annoys people and makes the community look bad and desperate.

SM63 =/= SMBX. They are very, VERY different games. Given the completely different physics, an SM63 runner would probably find running SMBX equally as hard as running, say, Legend of Zelda. Also, this game has a LOT of possibilities for speedrunning.

Do you not realize that SM63 has an editor? Also, after this, we should all stop replying because it's not going to go anywhere and the point is already closed.

Hey there, I personally did not know much about Super Mario Bros X. speedrunning, I had no idea there was a community around it. I see that you're trying to get people to run the game so good luck on that, the Super Mario 63 community went through the same phase at some time, so I do see why you're posting this.

Though as April said, this isn't really the right place to advertize runs for other games. Both games being fangames doesn't feel like, for me, a big enough similarity between the two games so the runners of one gets interested in running the other one. Advertizing on the SMBX forums feels much more useful to me, actually, so that was a good idea. I think some people do that on the main speedrun forums but I'm not entirely sure, maybe you want to check that as well.

So yeah, again, good luck to you on expanding your community !
