A cute story with a variation on the "It was all a dream" trope. As I read I was thinking, "this is trite!" but the ending shows why: the kids are fantasizing based on things they've seen or read. It also explains some minor irregularities, such as Vance having at one point a hand blaster and a rifle blaster, but later doing a tuck-and-roll with two hand blasters. It's all fantasy.

Rolling his eyes, Vance walked toward the house as Dave struggled to sheath his electro-sword through his belt loop. After the third failed attempt, he settled on tucking it under his arm as he followed along. "I suppose we could watch some tee-vee. I taped last night's Battlestar."

the way the above paragraph is structured, because you were last talking about Dave, I assumed it was Dave who said, "I suppose....Battlestar." The next line shows Dave talking so I had to mentally back up and re-think the previous paragraph. You want to avoid anything that bumps your reader out of your narrative; perhaps you could restructure the paragraph in italics.

I enjoyed the story.

My review has been submitted for consideration in "Good Deeds Get CASH!" .
