Making Starzard a sci fi version Spellzard

I am in the process of making a space sci-fi (or fantasy) version of Spellzard which I'm going to call Starzard.

The problems I met when making Starzard using Spellzard.

• Skill seems to be the main problem as it has problems when trying to implement space combat or vehicle combat.

It seems that I need to get rid of Skill and put a skill list similar to Warlock RPG but I don't want a whole list of skills. Maybe 7 or less would be ideal. If I do implement this what sort of skills should be on the list? Would it be easier?

Things that I'm keeping:

• the target number 14 
• skill test (which will be separated into an opposed test and an unopposed test, still rolling high though).
• Stamina and Luck generation
• This time player has the option to test luck if somehow they don't want to use their skill. (Maybe)

I might add some kind of special called traits which players pick at the beginning of chargen, just to differentiate them.

What do you think?
