Sims cannot become ghosts in The Sims 2 Castaway for PSP. The game omits supernatural life states entirely.
| Feature | Sims 2 (PC/Console) | Sims 2 Castaway (PSP) |
|---|---|---|
| Ghosts | Yes (death → ghost) | No |
| Aging | Yes | No |
| Romance/Woohoo | Yes | No |
| Supernaturals | Yes (expansions) | No |
| Open Neighborhood | Yes | Linear islands |
For ghost gameplay, play The Sims 2 (PC) with University or Nightlife expansions, or The Sims 3/4 where ghosts are full life states.
