I still prefer TNE's implementation of Contacts to MGT's implementation of Allies and Enemies.
And in an early version of my house rules, I used Events and Mishaps, only to move away from that because I've found the MGT implementation of them to be wildly varied from product to product, and oddly distributed. As they appear in the MGT core rulebook, I found that they don't suit T5 even if you adjust for the skill system. I love the idea, just not how it's implemented. I'm fiddling with several ideas, and something like it will probably show up in a house rules post.
