Having to wait 15 seconds for the ad, then have it load the game in half-screen, then load it again in full-screen, then have it stay at "Awaiting Snapshot" for 10 seconds because I go 999, then having to /reconnect and wait for it to load again, then finally getting in-game only to have big server lag because id never fixed it.
It's like they purposely made free accounts so goddamn frustrating that either you quit Quake or you just give up and pay.
