Plants vs. Zombies
Plants vs Zombies is a very mature and well developed game with few problems. Most problems are the result in unexpected conflicts with the Steam version.
Steam or Popcap version?
Both versions of the game are identical in terms of content. However, the Steam version regularly goes on sale, and also support Steam Cloud natively for the automatic syncing of save game data.
Steam problems
Save Game Corruption
Although the game supports Steam Cloud to sync save files the PC and Mac save files are not compatible with each other. Playing the game on one OS and then downloading it and running it on the other will cause the files to be permanently corrupted and you will lose all data. There are also reports of save data suddenly disappearing without clear reason. It is recommended that you make alternative backups of your save data just in case.
