FraterPerdurabo: Anyway. I should correct myself from earlier. It's not a terrible game. Hidden Path is working really hard at making this game accessible for everyone and it's not a bad entry-level shooter.
The problem that I have with it is that I'm not quite sure whether it's ready for competitive play yet (I last played it quite a few updates ago). It is, on the other hand, replacing CS 1.6 at most tournaments. We'll see whether it will be like the "Source switch" that occurred when Source first came out (most tournaments ended up dropping Source after a year and reverted to 1.6). Valve have even themselves said that this game was not intended for competitive play, rather it was supposed to bridge the gap between PC and console shooters. Most 1.6 pros are either silent and some are reluctantly changing over. I think most of them will wait out to see what the pro scene reaction to GO is going to be and see if tournaments will keep hosting 1.6 events if the reception for GO is lukewarm.

For me, probably the biggest annoyance is the lack of tagging. Back in 1.6 when you shot someone and the bullet hit, they would lose all their momentum and stop dead in their tracks. This lead to a particular style of gameplay that CS is famous for where positioning is important but really aim is king. It also lead to a much slower game pace.
In GO there is no tagging so running and shooting really is the core gameplay mechanic. It is difficult, if not impossible to punish people. This is much more akin to CoD, a very different shooter.

Also, I appreciate the fact that some people got bored for the arsenal of what like 7-8 guns but I don't think that GO is going to solve this "issue." They've basically added in a bunch of new weapons with randomly variable damage, accuracy and magazine size. Pretty much like 1.6. The thing is that once the game gets figured out (very soon) then people will resort to the same style - 3 pistols, 2 guns for low economy situation, 2 guns for high economy situation and a sniper. Voila. There will simply be no justification for buying one SMG over another SMG. Oh, also shotguns do a lot of damage, but I doubt that they'll see much popularity.

As a 1.6 veteran, I simply see no incentive to switch. Shinier graphics but weaker gameplay. Call it Source 2 if you wish.

Elmofongo: well since there will be obviously mods they might fix te game of the problems you said
