My suggestion is to use Android-like (Cupcake, Donut, ..., Marshmallow, Nougat, Oreo, Pie) version names for major releases, but using something else instead of sweet foods; for example GTA San Andreas things/weapons/places/vehicles/characters.

My example:
open.mp 1.0 "Andromada"
open.mp 2.0 "Burger Shot"
open.mp 3.0 "CJ"
open.mp 4.0 "Desert Eagle"
open.mp 5.0 "East Beach"
open.mp 6.0 "Four Dragons"
open.mp 7.0 "Grove Street"
open.mp 8.0 "Hydra"
open.mp 9.0 "Infernus"
open.mp 10.0 "Jester"
open.mp 11.0 "K-Jah West"
open.mp 12.0 "Los Santos"
open.mp 13.0 "Madd Dogg"
open.mp 14.0 "North Rock"
open.mp 15.0 "OG Loc"
open.mp 16.0 "Pig Pen"
open.mp 17.0 "Queens"
open.mp 18.0 "Ryder"
open.mp 19.0 "Sweet"
open.mp 20.0 "The Truth"
open.mp 21.0 "Unity Station"
open.mp 22.0 "Vinewood"
open.mp 23.0 "Whetstone"
open.mp 24.0 "Xoomer" (thanks Potassium)
open.mp 25.0 "Yosemite"
open.mp 26.0 "ZR-350"

I think it will be fun to make polls on the forum for what should be the next version name when it is about to be released.

What do you think?
