I've been trying to get tribes, until my PC is built I really don't feel like running it on my Macbook Pro. I use parallels to virtually run windows and lion at the same time...which really effects the playability of only MMORPG's (I played SWTOR a ton). So at this point, I'm just waiting on my final componets to arrive. =) I'll def be trying tribes out.
I've been playing D3 with a guest pass. So far, monk class seems pretty fun clickfest, but haven't got to any real tactical depth yet.
I love parallels but never successfully played good games virtually.
