HDBits is
HD only (TV/Movies).
For games you need to go to general/games
trackers (you can check the
tracker list)
General
trackers usually have better pre-time, since they will release mainly scene torrents.
Specific games
trackers are better for quality/long term seeding.
One that has not been mentioned, but I’ve heard that has some very good pre-times (I don’t own it) is RevolutionTT. Also
IPT,
TD and
TL are all very good for pre.
