I hear ya, man! I too only play when I can thus my odd times online. This means that I do not read a damn thing, I just boot and play. I understand that others have free time to read and master things, but I have never had that time. PSO is the oddest of all because in less than a year, I've learned more about the game than the previous 15 years.
I'd forget about the Q3 thing because if you do not have a BBA, most likely you will be target practice for the others. I was watching a Q3 video this weekend where the player was experiencing online speed difficulties as his connection was the worst by far of the other three players. There were so many times that the players were never where they were on his screen as he was not able to play in real time. Most Q3 players are using Pi's vs. those who have the Turbo (aka BBA) in which it is difficult to expect a player to play again when all you ever do is struggle just to die over and over again.
