Well I use Alphabetical as a basis but I apply some logic when needed
- All games beginning with 'The' in the title go by the following letter.
- Call of Dutys are matched by type - on PS3 I have CD3, CDWaW, MW1-3, BO1&2.
- I tend to place series within chronological order - so if a game has a PREQUEL like Halo Reach, I palce that before Halo 1 Anniversary Edition. So yes, Lighting Returns is after Final Fantasy XIII-2.
- If it's a bundle box, I go by the name of the collection or if it's just games by the 1st title on the box.
- If a game is a Spin-off I tend to put it within the Series it is connected to still Dissidia & Crisis Core still go with Final Fantasy ports on PSP.
