10x10 Gaming Challenge for 2015

So,

We are closing in on the 10 games we are going to play 10 times or more during 2015.

1. Castles of Burgundy
2. Founding Fathers
3. Keyflower
4. Robinson Crusoe
5. Saint Petersburg
6. T'Zolkin
7. Terra Mystica
8. Nations
9. ??????
10. ???????

The 10th game is still in the air since I would like to try a few of my unplayed games before deciding on the final slot. Machi Koro could fill in for the 9th slot but I still think it might be too quick for the challenge.
