Yes, I like P1 better than P2 (obviously). P1 is a great game, while P2 could hardly get much worse. Naturally, this is just MY opinion. You're free to like P2, as long as you don't try to persuade me that it's a good game.
For one thing, P1 was immediately seen as a part of the WC universe. It did not need an FAQ for people to accept it as taking place in the WC universe.
Secondly, P1 had superior sound effects. It had nice gun sounds, nice taunts (just to make myself clear, I don't mind the Bri'ish accents in P2. In fact, they give the game a very unique flavour), which P2 most definitely has not. It also has great comm lines from the civvies, which P2 MOST definitely has not (here I do mind the accents... when a dying pilot sounds like a lemming with a French accent, you know something's very wrong with the game).
Furthermore, P1 did not have stupid news articles that made the whole game seem like the parody of a space sim. And P1 did not have such idiotic things as a spaceship that will refuse to take off if it predicts boredom during the voyage.
Also, P1 had better AI, nicer ship designs, a better plot (yes, you heard right; the plot in P2 is nice, but in P1 it's way better... at least there was no evil twin brother involved
), many far more interesting locations.
And most importantly, P1 has no booth system! I remember you once complaining that in P1, the sales people, the bartenders and so on all looked the same. Well, P2 doesn't even have sales people. The booth system, you realise, was just used as a great way to cut production costs...
Is that enough, or should I try to come up with more?
I certainly could manage. After all, I haven't even mentioned the horrid flight engine P2 uses.
