What is the best mods to get for sfc 2 OP and sfc 3 that is most stable with least bugs,better graphics,better sounds,more ships ect.. ofr use in skirmish? Also is there one to add more ships onscreen fights at once instead of limited numbers?
For OP, the best looking mod right now would have to be the Hardcore mod that Pestalence is putting together. A testing server is up right now to help sort out bugs in the new mission scripts.
For SFC3, Legion At War 5 is the newest mod. Unity is alright, same with Island Wars. GAW was a great one, along with Final Frontier. However, GAW had some balance issues that were never really addressed, and it's been years since it's been touched or even had a server put up.
Depending on the mission scripts, the number of ships will vary for each mission. However, the limit of 6 ships in skirmish and PvP is hardcoded into the game code, for SFC2/OP/3, and I believe for SFC1, but I have never played SFC1 online before, so I cannot say for certain.
In SFC1/2/OP, the game code allows you to command up to 3 ships, which you buy. That's hardcoded, and can't be changed. In SFC3, you only command one ship, but as you move across the campaign map, you have the opportunity to have some AI ships fleet up with you, but only 2 at a time, for a total of 3 ships you can command.
