I don't think it's that trivial to set for the scripter. A listbox in AGS can only hold a maximum of 50 savegames, which is what we're at right now. Listbox max of 50 eh?  I'll avoid any snarky comments as complaining about a free game being developed on a free engine is usually bad form. Well, 50 ...

I know I'm a little late to the thread, but never late than never.

My vote would be to set it as high as possible.  I assume it's just a constant somewhere and therefore trivial to set.

If someone wants to have 4096 saved games, then so be it.  It won't crash the game or fill the hard drive.
