All games sooner or later come to an end. Closure of some sort whether or not win lose or draw. Baseball, soccer, football, track meets, tennis, monopoly, chess, poker, mumbly peg, ANY and ALL games come to an end. I propose that Dream World also join the real world and have a end point when the player's stats are archived in some sort of DW Hall of Fame and then their game stats are deleted, their place on the Top 100 disappears and they can then choose to either move on another game and seek fame and fortune elsewhere or start all over at Level 1 as if a brand new player - no carry over of stats, gear, gems, nothing but a brand new game.
To sum up:
1) As soon as you reach Level 100 (or whatever level the devs decide on) your game ends and your character and stats are archived into a DW Hall of Fame
2) Your game name and stats disappear from the Global Ranking
3) You retire and leave the game or,
4) You restart with zero everything, nothing is available from your previous DW game experience.
Yes I know people have spent real hard earned money in this game, rumor has it some have spent several hundreds if not thousands of dollars (or local equivalent). Yes, that's how it works in real life as well. You play to have fun and then you move on. Whether it be a graceful exit or a boot in the butt the game has to have an ending.
