Not particularly expensive but quite a few of the old games I have were developed before in app purchases and the free to play model. As such they were around £2.99 each and still function within themselves without need for server access or any app purchase within.
For example here's my list of 'dead games':
Command and Conquer, Snood HD, Game of Life, Monkey Ball, Anomaly HD, Slingshot, Caste of Illusion, The Settlers, TTR, Mirror's Edge, Jelly Defense, Peggle, Neon Shadow, Dead Space and Fur Fighters.
I'm cool with progress, I'm more annoyed when the developer pulls the old app and re releases a new one as free to play with ads etc - like Game of Life.
