  4. Reward Distribution

  5. Continuous Reinforcement • Duh! • A reward for every correct action. • Can be used incrementally for behavioural shaping http://lh5.ggpht.com/riya.reshu/SPNUthNHZmI/AAAAAAAAD_A/Uuhp-4DSimE/Shaping-Pen-stand.JPG

  6. Continuous Reinforcement The Negatives... • Most prone to becoming boring, as players can easily recognise it

  7. Fixed Ratios and Fixed Intervals • Fixed ratios • Simply a reward after x correct responses • Fixed intervals • A reward after x time has passed

  8. Variable Ratios and Variable Rewards • Variable Ratio • Reward the player after some number of responses (with an average number of x) • Variable Rewards • Reward the player with some amount of reward (with an average of x)

  14. What is security? Security: “the state of being free from danger or threat” • Oxford Protection: “the action of protecting, or the state of being protected” - Oxford

  15. Developing Security • If it is easy to add the security into your games ....... http://www.yesiamcheap.com/images/oldman.jpg

  16. Lazy, Cheap or Stupid? http://www.liquidmatrix.org/blog/wp-content/uploads/2009/05/vaderfail.png

  17. Lazy • We’ll add in security as it’s needed http://www.proactive-security.com/images/Realme6.gif

  23. Security Systems should be independent • This doesn’t mean bolt-on, it means manageable, and more importantly each system should be secure in its own right

  35. The Nintendo Entertainment System • The NES contains a lockout chip, the 10NES • IF it detects a fake cart, it sends reset pulses (1 per second) to the console via pin 4. • Guess the solution?? http://www.raphnet.net/electronique/nes_mod/images_lock/lockout_chip2_th.jpg http://4.bp.blogspot.com/_pJlwRrgGJfk/S-17HldW7AI/AAAAAAAAAVo/kvLQUOMlJx4/s1600/nes-console.jpg

  37. The EVIL anti-piracy techniques used

  38. http://farm4.static.flickr.com/3195/2782909930_a20527bfb4.jpghttp://farm4.static.flickr.com/3195/2782909930_a20527bfb4.jpg Lenslok 80’s home computer games Once the cacophonic banshee-wailing of the tape loading sequence finally came to a merciful end, the game would compound the player’s emotional trauma by flashing up a garbled two-letter code on screen. http://www.gamesradar.com/f/gamings-most-fiendish-anti-piracy-tricks/a-2010022516730628047

  39. Lenslok There were two problems: • The code had to be manually scaled to make it readable on different sizes of TV, and the system didn’t work with big or small screens. • The codes were incredibly easy to hack, given a bit of coding knowledge.

  40. Batman: Arkham Asylum Illegal copies of the game worked perfectly apart from one little detail. Batman’s cape glide ability was disabled, making the game playable but uncompleteable. http://ps3media.ign.com/ps3/image/article/949/949513/batman-arkham-asylum-20090129054204704.jpg

  41. Command & Conquer: Red Alert 2 After 30 seconds of play on a pirated copy of the game, the player’s base and units would detonate. Like recent EA DRM, the base blasting trick caused all kinds of problems, in particular blowing up the armies of plenty of legitimate players. Call it a pre-emptive strike just in case they were thinking of passing a copy on.

  42. Operation Flashpoint FADE detected pirate copies by inserting fake errors in the original game code, which CD copiers would clean up, making rip-offs immediately obvious Using a system called FADE Dodgy copies would let the game run Would gradually change the gameplay in increasingly horrible ways. Guns lose accuracy Enemies become bullet-sponges The player’s character would gain the battle resilience of a dead jellyfish.

  43. The Secret of Monkey Island • The game shipped with a cardboard dial, comprising two circles of different size set one inside the other. Each disc was printed with one half of a series of pirate faces. The game displayed the face of a particular pirate on screen, and the player had to turn the middle disc in order to line up faces and identify the year the pirate was hanged. Typing in the date allowed the game to run.

  44. http://static.gamesradar.com/images/mb/GamesRadar/us/Features/2010/02/Inventive%20copy%20protection/Metal%20Gear--article_image.jpghttp://static.gamesradar.com/images/mb/GamesRadar/us/Features/2010/02/Inventive%20copy%20protection/Metal%20Gear--article_image.jpg Metal Gear Solid At one point in Metal Gear Solid, Snake has to work out how to contact Meryl via his codec in order to continue the story. The clue is that her codec frequency is on the back of the CD case Cue the world’s unwitting Nintendites searching every object in the game for hours on end. http://blogs.ocweekly.com/heardmentality/Metal_Gear_Solid_ntsc-back.jpg

  45. Dragon Quest V on DS / Final Fantasy Crystal Chronicles: Ring of Fates The intro sequence in Dragon Quest V looped infinitely in knock-off copies. FFCC turned into a 20 minute demo, complete with a “Thank you for playing” kick in the stones from a couple of jolly Moogles at the end.

  46. The Silicon Dreams trilogy When developer Level 9 released its Silicon Dreams interactive fiction series in a bundle pack in 1986, it threw in a free, full-length novella as an introduction to the third game’s story. The book was also used as a password generator. The game asked for the word at a specific page and line reference whenever a saved game was loaded, and given that the source was a full-scale book, no-one was going to bother photocopying all of the content for a mate’s pirating convenience. It required a binary patch or a lot of photocopying
