its GP3-2000 and GP4 offline leagues.
Supported by extensive scripts, these leagues can provide a strong team
experience and some tough competition. Don't be fooled by the offline
nature, team work can be very intensive ranging from developing setups to
discussing race tactics, and extend over longer periods. Depending on which
team you will join of course :) And if you can't find one, start your own
team!
