1. Introduce something that kills the PKing community:
2008: Removal of Wildy (Its in 2007 but you get the idea)
2013: EoC (Didnt remove PvP but you get the idea)
Result: Negativity towards the game is at an all-time high. However, non-pvpers enjoy the update.
2. Introduce something that kills goldfamers.
2008: Free trade removal
2013: Botwatch/Optimus/Botnuke
Result: Paradise for people who depend on skilling for income, but haters increase their presence by stating that playercount is so low, game is dead, etc.
3. Add new Graphics
2008: RSHD
2013: RS3/HTML5
Result: Game is improved and is more competitive against other MMOs, but some players complain about nostalgia.
4. Add a new skill
2008: Summoning
2013: Divination
Result: Keeps high level players hooked in the game, helps to ease older players coming back, giving them reason to play. Haters complain skill is too different, etc.
(fast forward a bit)
5. Do some major fixes to PvP, bring back the PvP community
2009: PvP worlds/BH worlds
2013: ??? (Possible EoC and Wild revamps)
Result: PvP community retuns, player count increase, economy gets better, but then pvp community complains the game isn't how it used to be.
6. Add another skill
2010: DG
2014: ???
Result: More reasons to play, but community shifts to EXP waste mentality.
7. Do something desperate to revive the old game, to please the "nostalgia" folks.
2011: Return of Old Wildy
2013: OSRS
2015: 2011 server??
Result: The old players come back, then realise why they quit RS in the first place.
8. Jagex tries something completely new, which eradicates the PvP community once more. Return to step 1. Rinse and repeat.
And then we end up with this:
