Games (I know) that have functional invisibility are:
1. Titanfall 2
2. Planetside 2
3. Destiny 2
4. Destiny 1
5. ESO?
6. StarCraft 2 (Nexus wars) (or Parasite)

TF2 has the best one I know of. But in ESO it's so funny to use the Fighter's Guild mark ability that shows invis players, hilarious to see them panic when they notice they're visible way too late. Kinda the same feeling I get from playing with poison in Dark Souls.
