Games on a Shelf

I spent a little time collecting games from all around the office to try to put together a complete collection in one shelf. The boxed games I found scattered on a nearby shelf, many of the DVD cases were hiding in a secret place in a corner of the office, and the missing ones I took from our stash in the front office. Once I procured every title, arranging them on one shelf proved a little difficult. A few had to be propped up two-games deep, but it worked. Ah yes, organizing games is fun *cough* I mean work.
Looks like the weekend puzzle was a real tough one! Here's how to do it:
Puzzle part one: Use the [railroad] cipher to line them all up properly.
Puzzle part two: Use a variation of the [playfair] cipher. The hint "no keywords needed" means [make a 5x5 grid of the alphabet without shifting any letters. Group I and J together]. This cipher was hinted at by the "put them in pairs" clue.

Let's see if you sleuths can figure out the answer, before I give it to you on Monday. ;)
New puzzle comes tomorrow!
