Witcher vs Witcher 2

[rajpoot]

There is very little story continuation (negligible, even lesser than Mass Effect), since AFAIK Witcher basically wraps up it's own story and Witcher 2 takes off on a totally different and a lot more interesting story.
The gameplay overall, is a lot more fun. The sword fighting is a lot more fluid and action-y. The graphics are awesome, and the dialogue is better. Overall the game is not tedious at all.
On the other hand the number of monsters have been reduced quite a lot.
The game itself is average length, but depending on the choices you make, nearly two thirds of the game is quite different, story-wise (and to some extent quest wise), so you get replayability. This is actually something new CD Projekt have done...where player choices make a big difference.

And yeah. The game has matured, in one aspect atleast. Search Triss and Youtube and you'll know.

Edit:
Plus they're bringing out a new patch. Witcher v2.0. Adds a ton of content, includes all the DLCs released as yet, and it's free.
I mean if you don't get this game, you'll be missing something no RPG gamer should miss.
