You know, if you let me live in the Star Trek universe (pre-grimderp, that is) I would get myself a ship and putter around looking at shit forever. But my ship would be special. How?
It'd be one big holodeck! The theme can be changed. Starfleet Standard, Klingon, Vulcan, Romulan, Ferengi, the ship interior can resemble whatever I want. Hell, I could go with Victorian Steampunk or even a fucking cave if I felt like it.
Security? No problem, just turn the safeties off. The holodeck can simulate weaponry from phasers to bullets.
Crew? Several dedicated holographic characters controlled by independent AIs.
Just imagine beaming over to a ship and suddenly feeling like you stepped onto a 17th century British naval vessel but in space. It'd be awesome as fuck.
