Gave my vote. From what I saw you guys already had the basic gist of Ball Race, Accelerate and Mini Golf done so those should probably be the key modes to be worked on. Although in my views, seeing other game mode prototypes being done at the same time would probably pump people even more.
As for the rest, Condo Pets are probably going to be the best gem, since you would probably have something more to give life to your condo than just yourself. As for the rest, since as I play in groups, the grouping system has been quite helpful.
