I bought this one the day it came out. I personally think it's tougher than the first, but I can see it the other way too, since people who have played both were probably more ready to play SCPT than they were the original. IMO, Pandora Tomorrow is one of the best games on the market. The gameplay and the HUD were tweaked and slightly improved. Overall, I liked the single-player experience slightly more in Pandora Tomorrow than the original. The gameplay is thought-provoking and engaging, and the online facet of the game is revolutionary. If you have XBL, this game is essential. I haven't seen the PS2 version of it, but I remember the first one was dumbed down graphically , and I'd imagine the same is the case on the second one.
