ABCs

Inspired by a naming competition done by the Giantbomb crew to pass the time while they signed posters on a live stream for something like 3 hours, I decided to play alphabetical categorization with video game titles too.  Here's the basic ground rules:

1. There must be three entries all with matching first letters in the title (excluding "Y").
2. All entries must have been played at some point (by me).
3. Connecting words don't apply to rule #1 (such as "the","and", "of", etc.) 

Now let me sing you my video game ABC song (with links).
