Best - Hard to decide. Zelda, Persona 5, and Uncharted 4 all round out the list for me.
Worst - Out of the ones I've played. MGS 5. Very disappointing. I also have a personal hatred for Overwatch even though it's an objectively well designed game.

Thread Titles:

• Need to accurately describe the subject content.
• Should not use deceptive hooks to lure people in.
• Should not be used to pose simple questions.
• Should use full names rather than abbreviations (StarCraft instead of SC. Star Control 2 instead of SC2. Soul Calibur 3 instead of SC3. SimCity 4 instead of SC4).
• Should use proper capitalization (no CAPS), grammar, and spelling.
• Should not include inappropriate/foul language. 

With that in mind, I'll be locking this thread.
