Well I have six. One more than you said but I figured it was close enough.
1. I have a Tron LE, GotG LE, WOZ ECLE, original restored MM, original restored MB, and a AFM r LE.
2. Small collection because after having 30 games, I realized the money sitting was better utilized for a family beach condo. Much more enjoyment having a summer place to enjoy with the wife and kids. We still have games to play and have fun with but I believe you really don't need an enormous collection.
3. I like the lineup and it has stayed the same since I sold 80% of my collection and bought the condo. I did add the AFM r LE and the GotG LE so my ideal collection of 4 turned into 6 without anything going out the door.
4. The kids and I like the collection. Something old, something new. Monsters, Aliens, a fun movie pin, a classic movie (that my girls enjoy) pin, a pin that immerses you like no other so you feel like you are on the grid, and a comical castle bashing pin that has dragons and damsels - something for everyone.
