It has to be popular enough to last for a long time and have many entries, while appealing to my tastes. It can't be in decline either, to make sure it remains a quality series.

I'll go with MGS. I prefer two good MGS than eight good GTA.
No troll is too much for me to handle. I rehabilitate trolls, I train people. I am the Troll Whisperer.
