Demands half of your life.
Compared to Quake 3 Arena (Which just had Deathmatches), This game has many modes. So the game is not at all repetitive. A feature of playing with player-set bots, with a choice of match settings and an array of maps - This game still betters many games (Like CS, Quake 3 Arena) of its genre.
Being a game of the 90's, the game has superior graphics which does not make a player to refrain from playing this game even today. Unmatched gameplay makes it more fun to play than games releasing nowadays.
The choice of weapons is also better than many games standing in its comparision - The Flak cannon owns gore.
To add more - The G.O.T.Y edition of this game has made the game flawless and a great package - With texture enhancements and 2 great mods with loads of maps - Which has bot support unlike Quake.
This game is worth a buy even today - Its the best in Unreal series, so prefer buying this one instead of any newer ones that are definately inferior to this epic title.
