My oldest son is turning 2 at the end of this month and I've started to contemplate exactly how to follow through with my plan to mold him into a sci-fi geek. It's not that I'm big into sci-fi myself (though I like it, I'm not a fanatic and didn't grow up with it), but a kid's gotta be into something, and sci-fi geeks always tend to have more interest in more worthwhile, cerebral pursuits.

In any case, I figure Star Wars and/or Star Trek should be a part of his upbringing, though I won't introduce him to those things for a few more years. I just got to thinking about which one I should get him into first, then I started questioning if it should be both or just one or the other.

Everyone I've ever known of who is very into one or the other is always into just one or the other. Is that necessary? Can someone be very interested/invested in both franchises? Or can you only immerse your imagination into one pretend universe?

Are any of you hugely into both Star Wars and Star Trek? I also wonder if I should get them into comic books and D&D. Do you have another other thoughts on what else I should do to mold my sons into quality geeks?
