This collection is wonderful and is one of the best classic HD collections on the PS3.
The first game is an amazing game and I have played through it 4 times already. It is a timeless classic and reminds me of Aladdin.
This game must be played and enjoyed as it is by far the best game in the collection. The graphics are also great and the story is engaging and compelling.
Having never played the second game when buying this collection I had high hopes. However, the reason I knocked a star off the rating is because Warrior Within is by far the worst game I have played. It ditches the wonderful setting of the first game and moves it to a dark, disturbing and lifeless underworld. The game has no emotion and is a disaster by all accounts. The prince is unlikeable in this game and the whole world in this game is a total disaster. However, the worst thing is that when I got to the end of the game (which was torture) the game contained a glitch right before the end boss which meant that the whole game had to be restarted. There is no solution for this problem apparently.
On the other hand, Two Thrones, the 3rd game is a return to the brilliance of the first game. It is an engaging, well-thought game and will keep you entertained. The dark prince is a great addition and has some wonderful moves. The story is also brilliant. However, it must be said that the game doesn't reach the heights of the first game. But do not be fooled, this is a gorgeous game with wonderful gameplay and graphics.
One final mention should be made to the audio in all three games. The audio in sands of time is amazing but there is a problem because the ps3 version has a lot of freezing in the audio and just doesn't sound right (characters speak as if they are in the bathroom). THis is a minor quibble but should be mentioned. Warrior within has alot of rock music which is disastrous but Two Thrones returns to the old classic music.
All in all, this is a brilliant collection, but I would recommend that you do not play the second game and skip straight to the third game. The second game really has no place in the sands of time timeline. (but to understand the story of Warrior within visit youtube or wikipedia to have a quick read through it as it is useful to know before playing Two Thrones).
