My two faves have got to be Spectrek and Zombie Run! Both games are GPS enabled and both require you to get off your arse and get out side running away (zombie run) or searching for ghosts (Spectrek). I always play at night as it's more scary and fun, and the neighbours wonder what the hell your doing. The other day I ended up in some private allotments shooting a ghost and walking over their cabages (so don't go out get pissed and think you could just nip over that wall on the way home!!!) Are there any other games out there that are like these???????? I've already seen Parallel kingdom, which is o.k. but complicated if you like that sort of thing.
