So we all know that racing isn’t really in halo anymore, but let’s just say it did return. Could it be a possibility to actually have a racing gametype to play over xbox live? I feel like that would be an awesome thing. I also have heard ideas of a custom gametype with custom games/ gametypes such as cops and robbers and all those fun things that could be included with the racing. any thoughts? 
Racing would be a great idea for XBL. I wanted that in Reach really bad, with all of the awesome community maps, there would be endless racing fun! Not to mention if someone gets frustrated with regular slayer multiplayer, they could just race for a while.
Considering they removed the game type altogether I don’t think they will have a racing playlist. In my opinion a race playlist could be successful (if there was a game type), but I wouldn’t expect them to choose proper settings and maps even if they did.
I have Mario Kart 64 remakes on my file share (THFE feature #49)
