Hello Astner,
Welcome to NamePros.
Since your plan is for a hobby / entertainment site and not to earn money then paying for the com isn't really needed.
Although you will leak traffic to the com, since it is a bit of an obscure keyword, building out a decent site while the com is parked shouldn't affect your visitor traffic enough pay even the 5k for the com.
I mean seriously, how much direct type in can omnipotence expect?
Anyways, this is jmo, and others may disagree, but building out the site on the net should be fine..
As to your original question, 75k.. that's a lot for this keyword because as Brad mentioned, it's biggest value would be as a Branded name, and the seller can put whatever price he chooses. You can always come down.
Good luck with your site, I'd really like to see it built out and what your vision is for this domain.
Peace,
Cyberian
