I don't know if this idea has been brought up before (for all I know it's a feature of practically every mod out there) but is it possible to have open-ended tech levels? For example, in the normal game there is a limited number of levels of cloaking (3?) with a slightly larger level of scanners. Would it be possible to create a set up where there is no maximum limit to the level of cloaking and scanners, where there could be a constant race between the two technologies? It seems that something like this could be interesting for cloaking, scanners, ship sizes, shield and weapon phasing levels, etc.
I've looked at the various text configuration files, but there doesn't seem to be any obvious way to do it. I suppose a similar effect could be achieved by manually adding in an incredibly large number of levels (I've seen the ultimate ship size mod -- very cool) but it would be nice if there was a way to just set up certain tech areas as being unlimited.
Or maybe my games just Last too long.

One of the things I love about SEIV is how *big* it is, compared to other space 4X games. So many systems, planets, players, technologies, etc. I'd love to see a game that had infinite levels in all of those areas (subject to memory limitations). I suppose empires with thousands of planets would be impractical for multiplayer games, but they'd be fun for singleplayer ones.
