I'm sure there are plenty of gamers out there who've never played the original Unreal, nor the great Return to na Pali add-on pack. The original Unreal was scandalously overlooked, firstly because it was released close on the heels of Quake 2, and secondly because on it's initial release it was crippled with huge numbers of bugs (this does NOT apply to the Anthology edition, I should point out). However, Unreal featured graphics and sound that were, for it's time, absolutely breathtaking. The first time I played the game I literaly spent 5 minutes staring open-mouthed at the beuty of the SKY. It was that good.
Add in a compelling story, brilliant AI (the Skarj are serious foes), great sound & music and the original Unreal was a truly great game experience. Oh, and as far as I know it was the first game to feature bots in multiplayer out-of-the-box. Return to Na-Pali added more great single player fun to a game that still provides a worthwhile playing experience today. How many games leave you speechless with moments like Bluff Eversmoking? (Play it, you'll see what I mean - it's still a great moment even today.)
Next came Unreal Tournament - the game that more or less started the whole on-line-only shooter fest. It did and does however include a worthwhile single player mode. The number of maps, mods, conversions and even single player add-ons for the original UT is now more or less endless, and though by modern standards the graphics are dated, the game remains great fun.
Unreal 2 provided an excellent step forwards in terms of the game engine and included a great single-player experience. Didn't have that much in common with the original Unreal, but was an excellent game in it's own right that deserves to be played. Includes multiplayer that I think eventually had an add-on with vehicles.
UT2004 is probably the best known of the games included, and arguably is the best. UT2K4 had (and to a large extent still has) cutting-edge graphics and all the fans' favourite game types, characters and weapons from the original UT. Like it's predecessor, UT2K4 has spawned a vast number of maps, mods, single player campaigns and conversions and is fantastic fun both on and off line.
The four games would be fantastic value on their own, but add-in the opriginal Unrel music CD by Straylight Productions and this is an unmissable combination. All in all, awsome and genuinely engaging single player experiences mixed with the absolute best of multiplayer make this pack a must-buy.
