Although there are plenty of other threads that people may find interesting, chances are they will be relatively short-lived and will be completely forgotten in a week.
So yeah, great basis for discussion. I think this will probably be one of those that is forgotten in a week…
Whether you like Honda's or not, you should check it out as it gets pretty interesting sometimes. Keep coming back too because if you don't keep yourself up to date, you miss out on major stuff like Punk Rock/Fred did.
I'd say some of my favs are the...
General Anime Thread (Movies and TV forum)
"Is GT losing the battle to Forza" (GT5 forum)
Tuner Garages (GT4 forum)
PS3 General Discussion (PS3 forum)
That's about it right now but there are a few that come and go as favs. Stuff like the occassional movie thread, political thread, rumble strip anything, and even the various "ask gtplanet" threads all take a spot as one of my favs at some time or another.
My Dorkdom thread is keeping me entertained as of late, but its hard to pick a clearcut (much less a thread that sticks) winner. I really can't I guess, as I float around quite a bit, topic to topic from time to time.
