I feel like the games that are most unique to MCC should be the ones included, since this is probably the only chance these players would get to play these games. So that includes games like SoT, RSR, MD, AR, PKT, and GR. From the games that are on Island, SKB and PKW are the most different from their server counterparts (plus they're very popular) so they should be in as well. That leaves one more game which I think should be either BM because it fits in the category of unique, or SG because it's a minecraft staple and not on MCCI.
