ERROR: Today has not been given a definition. (In particular, I could fall asleep now and still get up early for a reasonable definition of "early".

The next person sometimes prefers experimenting with a game (for example, testing things to see how the game behaves) to actually playing through the game normally.

Yes Yes Yes, totally, Absolutely, essentially! This is mostly for games with many glitches and exploits, like Baldurs Gates originals, for example.

Next person started recently Diablo Lod on Battlenet, again.

Oh no I spent enough time on Diablo 2 in my youth. Got all characters to level 99 in version 1.07. I am not wasting any more time on it.

Next person got to work late today because he/she missed the bus.

No...  I'm self-employed and I have a car...

The next person slept very badly last night or had a scary nightmare.
 

Don't think it was last night, but had a nightmare that by brain seems to think was about Scientology.

However, I have not been involved with Scientology or even seen it in person.

(I have, however, read about it.)

Next person has at least once created a computer game or a mod for one.

Sadly no. I use to skin characters years ago but bothing of the sorts.

The next bloke is not a bloke...

No! Actually, me, being the next bloke, i AM a BLOKE! A TRUE bloke, hardcore!

Next person doesn't know what bloke means, he he...

Being English I most certainly know what bloke means.

The next person is scared of monkeys.

Absolutely not! I loathe dogs, especially given their tendency to bark.

Next person, when given the option, prefers to play female characters. (Assume there are no gameplay differences between the genders.)

I prefer an implied dick on my dudes, sorry.

Next person has never eaten quinoa.

True and it is a shame, really, since i dabble in kitchen (and healthy diet) a lot, lately...

Next person has eaten up Giros (traditional greek JUNK food) and loved the stuff!

I don't think I have, though relatives probably have. (I'm half-Greek)

Next user can, at will, get any song or piece of music that she knows well enough going through her head. (Essentially, like a photographic memory, but for music rather than images.)

Spot on! I can do that with so many songs.

Next person does not like deus ex.

It's too cumbersome. I just wanna shoot stuff!

The next person used to prank people for fun until one day when he/she just lost interest.
