Complete off-topic, but everytime I see the topic I must think of the Apple IIgs because the Illicit, like it's another model..

As someone who works in IT support for a multinational company, I would say it would easily be possible to be fired for gross misconduct for installing and playing games during work time. Equally it may be fine - at my first job we spent lunch times playing CounterStrike over the LAN. Only you know your employers...

You have a similar decision to make. Hopefully if you make the wrong decision, you won't lose your job.

It doesn't make it more legal, it prevents it from being flagged.

For those who are up to some illicit gaming at work, Sierra's early Quest games are almost perfect for staying undetected:

- sound isn't necessary
- modern machines can run them effortlessly without memory/processor spikes
- they can be run from a flash disk without installation
- quick alt+tabbing if someone approaches
- frequent typing in commands make you sound like you're actually working :D

For visual deception, try text-only adventure games. They're difficult to distinguish from work-related stuff from afar. ;)

As a few others have mentioned, it's over-zealous IT co-workers you need to be weary of.

It also depends of the nature of the game..... I used to create bespoke reports and at the time the servers will chug away retrieving the data I queried and the results were far from instantaneous. During the time I was waiting, I would play Drug Wars (anyone remember that?). There was an avatar of the dealer in the top left (I think) and I'd hide that part behind a task manager window, so all that was visible was, predominantly, numbers. However, on close inspection there would be a list made up of the likes of Cocaine, Mescaline, Crystal Meth etc..

So, in short. Yeah, it's ok morally and technically to run a small simple game. Anything beyond is treading on thin ice.

I can pretty much get away with playing what I please at work, but I often stick to ye-olden-skool roguelikes as they, at first glance, look like work. I play a lot of Brogue to be honest.

That's because they often are very hard work. :D
