I've played every version of Cycling Manager since the first in 1999. It is an awesome game. The best versions made are Pro Cycling Manager 2006 and Pro Cycling Manager 2008. I don't think it is buggy at all, especially with the current patch. I like to add me into the game. Makes it even more interesting. I'm a classic rider (in game only). I get all of my updates and extra's for the game from http://www.pcmdaily.com/news.php
Just need to register first, but heaps of nice add ons for the game.
Initially it takes a little while to plan your year ie. when your want your riders to peak, etc.
for those who find it too easy to win, some suggestions, move the level up to Hard. I still can't win much on Extreme, so play on hard where I win lots but still hard to win all that I want. Keep the stats of your riders realistic or even slightly lower. Don't do the training camps just before the TdF. Don't attack on the downhill or mountain close to the finish line. Unfortunately they haven't made the AI to attack with you on the downhill, which would have made the game perfect if they had of.
Also if you play online, the cheats make the online AI passive and attack with their whole team at the beginning. I find it better if you let the AI do their thing on easy or medium. Makes for more realistic online play.
