Wormholedrives and stardrives

[jars_u]

I like a lot of Klauss engine ideas. But, the cost issue is the big thing if you have to spend the time researching so many different tech trees what you save in actual resources off sets that. However, I do think it does add another strategic aspect to the game forcing players to pick their techs more carefully. I think fighters should always been short range/in system travel only but I think the in game engines (i.e. your worm hole drives) and in system engines already cover this base. But, the stardrive is an interesting idea if you have ships that can bypass wormholes totally and jump across more then one system at a time then in would be really stupid to leave your home systems un-defended no matter how large your borders/empire is.
