Tony Hawks Pro Skater 3:
Snipes server: It will 1st say failed to connect but then take u 2 the lobby list.
Bobz server: U will get the message of the day and come to the lobby list, the only bad thing is that bobz server is slow so u may not be able to connect to gamespy the 1st try.
Xlink Kai: It works great with Xlink Kai, but its very hard to install and almost no one is using it.
How many is playing:
That matters, this is a dead game online right now, because most people does not know that this game still works online because it does not have a DNAS patch. But it would be fun if we could find a way to get more people online.
Tony Hawks Pro Skater 4:
Snipes server: Works great and the server is fast and never freezes.
Bobz server: Bobz server is really slow, it takes around 5 minutes to get connected so i can recommend using Snipes server.
Xlink Kai: The game has a lan mode but its kinda worthless to use it when you can play on this new servers.
How many is playing:
Defenetly more than in THPS3, here you may find players daily playing, but around 5 people at most are there daily without giving anyone tip or asking one to play.
Tony Hawks Underground:
Snipes server: Wow! Works good as hell with snipes server, you can still do face mapping, http://thps.us/faces.php.
Bobz server: As it is in THPS4 it is slow here also but face mapping works here also.
Xlink Kai: The game does have a lan mode but as it is with THPS4 its worthless to do it.
How many is playing:
This is the place there its around 40 people playing daily, here its always someone to play with and i really like that, but most of them just wanna style and that sucks.
Tony Hawks Underground 2:
Snipes server: Works great and fast, just freezes sometimes when you are in the lobby list.
Bobz server: Slow but never freezes, but it takes time to get to the lobby list.
Xlink Kai: The game does not have a lan mode.
How many is playing:
This is more dead then THPS4, theres almost no one there, i have met around 5 people there. I would really like to find away to get this game more active online.
Tony Hawks American Wasteland:
Snipes server: Fast and good, the game is never freezing here, but in THAW you can not do face mapping because of it uses a different face mapping code.
Bobz server: Slow but good, but face mapping doesnt work here either.
Xlink Kai: The game does not have a lan mode.
