The games are arranged in alphabetical order, except for four titles: Iron Storm, Master of Orion 1+2, Heroes of Might & Magic 2 Gold, and Oddworld: Abe's Exodus.
The first letters from each of these titles spell out: I M H O.

The answer? "In My Humble Opinion"

The games are not related to the contest in any way.

Title: The Alphabetical Complicated 30.

Day 2 hint

"consider the titles, read them through
the words and the letters hold an answer for you"

Answer: They are all related to the company Infogrames (now known as Atari).

I have no idea, so i'll post this.
The connection is black metal nonsense lyrics. One word from each title forms this:

Insane rising of Dark magick, The Divinity Castles,
The Duke tactics storm Independence.
Shadow wildfire of crime of Lords Of Three rule two nations,
Kingdoms Sorcerer! Overseer! Unreal Oddworld awakening!

Answer: You think that Unreal Tournament 2004 ECE is the best of the 30 games listed.

Reasoning:
All of the games listed are in order except:
Iron Storm
Master of Orion 1+2
Heroes of Might and Magic 2: Gold Edition
The Nations Gold Edition
Oddworld: Abe's Exoddus
Unreal 2: The Awakening SE

The first letters all put together are:
IMHTOU

But then we need to put them in order. First by player modes in alphabetical order, then by genre in alphabetical order.

(meaningful letters in caps)

So first, *M* ultiplayer games, then by genre:
Iron *SHooter*
Master *Strat..Econ*
Heroes *Strat..Turn*

Then *S* ingleplayer games:
Oddworld *Action*
Unreal 2 *SHooter*
The nations *STrat*

So, in order of players ("game modes") by alphabetical order and then by type of game ("genre") in alphabetical order, it spells out:

IMHOUT

In My Humble Opinion, Unreal Tournament

The Unreal Tournament 2004 ECE game is shadi.lahham's favorite, in his humble opinion.

You should get the free game if only for creativity and effort alone! :)

You mean that's not the answer?! I thought for sure I had it.

Oh well. Back to playing some games. :D

civilization 3 is from infogrames

Day 3 hint

"Two by two, two by two,
see the pattern that pairs reveal to you"

The games companys are paired together. Epic games for eg are adjacent to each other =D

Damn, if I knew there were going to be daily hints I wouldn't have spoken so quickly.

Tell me about it.

You're right guys. I did not mention that there would be daily hints.
