I've just finished the 2nd play of
Witcher 1. At first, I could not manage well with the unique rhythm battle system in the game, but eventually, I got used to it, and I think it is actually a better way to express Witcher's superhuman ability in the battles than the usual action battle system in 2 and 3.
A weak point of the game was a limitation of the game engine (I think it is the Aurora Engine, which was made by Bioware and used in NWN2 (EDIT: actually NWN1) ).In the game, Geralt can't jump or go down bumpy fields. There are a lot of areas which he can't go on.
Also, I think it is due to the Engine too, sometimes the game shut down itself without any error messages, so I need to save the game often to prevent frustration.
In the first play-through, I chose the knight order faction, so in this game, I take a side of Scoia'tael. I guess this decision will affect the play-through of 2 and 3 too.
I'll play the 2nd one eventually, but before that, I'll try 7 new adventure modules (I guess they are former mods) in the game.
