Sick of Sudoku

Ive played alot of games on pocket pc, yet there is one game i cannot stand and that is sudoku. Yes i know its that number or letter based game where the number and or letter cannot appear in the same row twice. What i dont understand is why there is so many versions of it available for pocket pc, the game itself is so simple you could use pocket excel to play it yet if you search on Handango youll find there is over 100+ listings for this basic game... (as seen here...) instead of putting all that effort into making more sudokus why doesnt someone release a few more RPGs i say....
