Making its debut in 1998, the first generation Unreal Engine integrated rendering, collision detection, AI, visibility, networking and file system management into one complete engine.

With the level of integration used, some trade-offs were necessary to maintain performance levels with the hardware that was available at the time.

For example, Epic decided to use cylindrical collision detection over the IK collision detection system in an effort to maintain playable framerates on systems that were common at the time of its release. Internally, Epic used this engine for Unreal and Unreal Tournament.

Big thanks to Epic Games who have joined the 2014 Mod and Indie of the Year awards. Every year we recognize some of the hardest working and most creative game development teams in our players choice awards. Many do it for the love of the game (especially the mod makers), so it is great to be able to give something back. While our focus primarily is showcasing and promoting all of the mods and games on the site (as we know nothing beats finding new players and fans who appreciate your work), Epic Games have offered something a little extra.

At the conclusion of the awards, 100, 30 day engine subscriptions will be given to the players choice top 100, and 10, 12 month engine subscriptions to the players choice top 10 (in both mod and indie events). That is 220 Unreal Engine subscriptions total worth a combined $8000. The winners will be contacted with their code via their development groups email address (or member email address) after the top 100 and top 10 have been announced.

Oh and for those who are not creating a game or mod and are just here to play, we have G2A.COM giftcards for mod voters, so don't forget to vote and check back on December 11th for the top 100 to give yourself a chance to win. Xmas 2012 Mapping Contest

this really need to be rewritten first it says this :

32-bit colored 512x512 size texture support

then further down it says:

High resolution texture 1024x1024 size support

i know for a fact that the first release of this engine only supported up to 512x512 textures and only later in 1.5 they included the 1024x1024 support
(never released only for tech demos)

The thing is -- Unreal and UT99 used raw UNCOMPRESSED textures!
Imagine that!
The engine actually could support much higher res textures at that time :D

The mother of the Unreal engine tree, which is the most used one by video games. It does a good job in both Deus Ex and Unreal Tournament.
