TW1, too, so far. I guess it depends a lot on which one you played first. For me, TW1 was completely unexpected, new, complex, mature, dark, original, sarcastic with a great sense of humour, great main story and fantastic secondary quests, unforgettable and believable characters (often well defined with a single line of dialogue, like Foltest: - '..I'm a fucking king!' :)))))), open world, interesting reward system for the secondary quests (sex cards, waaaaay better than any illogical increase in character's stats) and so on - it just hammered me constantly :))
TW2... not so much. I mean - OK, there is still a complex story, it's visually better; the dialogue/choice system is way better etc. Some actors do a better job, others a worse job than the ones in TW1, no change here. The sword and magic fights are mostly the same too, only look and feel a bit different. And so on. There are some bad choices too - the infamous inventory, for instance. Speaking of feeling the game, I couldn't find my first and only love, Shani :D. But I had the chance to atone, instead, for some heartbreaking decision I had to make in TW1 (betraying the elves and dwarves and Triss... ) and eventually to find the meaning of life :)) I mean - in the end I didn't care at all about politics, kings, assassins - I just wanted to honour some promises I made to some people and to help Triss, who never gave up on me (Geralt, I mean), even after me (Geralt) being an asshole in TW1. All in all, it should have felt almost the same, apparently.
But it didn't. The incredibly 'real' elves (so much different from what one knew after watching The Lord of the Rings...) are still there, but they are not new and stunning as in TW1. The fantastic atmosphere is still (somewhat) there, but it won't surprise you anymore as in TW1. There is no more Lady of the Lake, or the Dryad. OK, there is still the lady Dragon, but... And there are still the hilarious NPCs, but... Well, they are not unexpected anymore and not as many as in TW1. The magic is somewhat gone. What would make it work for me the same way TW1 did, would be a TW3 to give a sense of continuity, to reveal the 'greater truth' that makes Geralt tick, in an epic way. Right now, TW2 seems more like a stranded episode, with no real sense of what I’m (Geralt) doing there and why. I’m just a guy trying to make sense of my own existence, but with no real purpose (the ‘remembering’ thing, the Wild Hunt, Letho and so on might be satisfactory for some people, but they don’t really give me a feeling of greatness and awe so far, mostly because they are unfinished businesses yet). Overall, TW1 was a story by itself, TW2 is just an episode in a larger story and I can’t truly make any comment here, because... I didn’t finish it yet. Everything changed when (as mentioned above) the premises were gone and I didn’t care about them anymore, but found new ones for my actions. This may be fine or bad – everything depends on TW3, which MUST come, now, to complete TW2 and make it a better (or worse) experience than TW1.
Perhaps I should write a review? Oh, wait, I just did it! :))
