A handful of the people on this site and I have been playing Timesplitters: Future Perfect with LAN tunneling (Xlink Kai) for years. We usually use the settings listed below when hosting as we find it makes things more fun. Of course this is partly a matter of opinion, but with these settings the most people usually seem to be happy.
Our Most Played Game Mode= Deathmatch
Deathmatch is the game mode we play most times as it is fun with small player counts as well as big ones. These are the settings we use with it.
Hosting options for Deathmatch mode through LAN

Score Method: Kills-Suicides
One Shot Kill: No
Time Limit: 10 mins

This game really wont be fun for very long if you have 2 players. The only maps that will work decently for that is sniping maps. Siberia is the only sniping map really (unless you have mapmaker sniper maps of your own). After a couple rounds, 1 vs 1 sniping gets old very fast.
But if you manage to get a third player the game is a blast as there are a ton of maps that are fun with 3 people.
Maps for 3 players
Siberia (if you all feel like sniping)
Work fine with as little as 4 players, but funner with 5 or more
middle sized maps, probably want at least 5 people
Maps we rarely play, so can't say yet what is a good player count for sure
Vietnam (a pretty big map)
Bunker (middle sized map, seems like would be ok after 5-6 players?)
extremely large map! wouldn't try it unless you have near 8 players
The creator of a mapmaker map obviously has a huge advantage over other players because he knows every inch of the map. So this can piss people off if you host them without asking. So just ask people if they feel like playing a mapmaker map before you do and everyone stays happy haha.
Also, keep in mind the size of your custom maps in relation to the player count that night. If you have some really gigantic awesome map it won't matter much if you only have 2 other people to play it with. It will just get boring since everyone will spend most of the game searching for other players.
Another thing to keep in mind is that mapmaker maps with lots of big open wide spaces tend to make the frame rate drop.
Magchargers are very annoying to have in the weapon set since they can shoot through walls. The secondary function of the weapon shows you every enemy location and lets you zoom in and snipe them through walls. It is way too easy to do so, which results in people walking through the level and repeatedly dying moments after spawning since they are defenseless against people camping in corners of the map with the magcharger.
Proximity mines can be every annoying because like the magcharger they encourage camping. Most times when this weapon is available people toss them all over the place on all entraces to the room and simply wait there until someboy walks into their mines. Even when they don't do this, the mines really break up the gameplay as you are focusing on the combat in the game and its way to easy to miss the mines and randomly die by stepping on one of the dozens of mines that have been tossed around the level.
Because these 2 weapons have such a negative impact on the gameplay, we tend to make sure that we never pick a weapon set that contains either. This can be difficult though because lots of recommended weapon sets for maps contain them and even some random weapon sets you can choose do.
So to help people pick out the weapon sets without these weapons, here are some lists:
The only maps whose recommended weapon sets do not contain Magchargers or Proximity Mines are:
These maps' recommended weapon sets have either Magchargers or Proximity Mines (So don't pick the recommended weapon sets for these levels)
Vietnam: proximity mines
Hotel: proximity mines
Subway: proximity mines
Spaceport: proximity mines
Bunker: proximity mines and magcharger
Other Weapon Sets without Magchargers or Proxmity Mines (can use on whatever level you want)
Other Weapon Sets to avoid:
Neon (has magcharger)
Explosives (has proximity mines)
