CP and Interlock were both on my list while I was shopping for a new system before landing on HG/JC. But the idea of building all of the space ship stuff was too daunting.
With Silhouette, everything in Traveller (2d6 rules) ports over without a problem... because I'm lazy and it worked for once!
Yeah, I flipped over to Full Thrust for ship combat (actual FT, not PP) and just kinda otherwise treat ships as scenery.
