Uplink/YMMV

Game Breaker:
- The chronic insecurity of the Inter NIC server makes life a little too easy.
- Calling the Inter NIC server's insecurity 'chronic' is like calling water wet, to emphasise. However, there's still the Uplink Test Server that you can break into to cover your tracks.
- Bah, that's basic. Do a Trace balance transfer mission involving a large cash amount. Note your bank ID & IP, get back to the account of the TBT mission, transfer all of them to your account, delete transfer log, disconnect, then delete transfer log at your account, then clean all bouncing logs. Voila, you now have money to buy everything you need (if the money is more than 200000). Of course, given the short timeframe for deleting all the logs makes it really easy to get caught, makes this a Death or Glory Attack. But, hey, high risk, high reward.
Good Bad Bugs: Early versions of the game had dead or arrested people answer their phones like nothing was wrong. Also, phone calls would sometimes play in Slow Motion, which just sounded ridiculous.
Paranoia Fuel: You won't know you've actually done something fatal (or at least extremely inconvenient, if you've got a motion tracker and explosives and enough cash to restart) until you get a sudden blank screen.
That One Level: For some people, hacking into a LAN. Unlike the rest of the game, navigating a LAN means playing cat and mouse with the server administrator and navigating all the hardware: using subnet masks, lockbreakers, and all that jazz. Now enjoy doing it three or four times to the same LAN in order to retrieve several hundred Gq of data, then delete the local copies and upload that data to a server for another corporation to use! Mmmm, corporate espionage!
Unwinnable by Insanity: It's possible to render some of the data retrieval missions unwinnable by purposefully vandalizing and wiping everything on the servers you hack.
