Previous Saves Data?

Does anyone know if the game will read, let’s say for example: I played Halo 1, or Halo: Reach on my account?

Not sure if this has been asked before, but with the influx of games doing this already I thought it’d be interesting to know.

Ummm you won’t be able to use your Combat Evolved save data if that’s what you’re asking. As for Halo Reach, all of your data is linked through your gamertag
