The actual social aspect of social games is often discussed frightfully little in social game reviews. This is because most social games aren't really social at all, at least in the sense of having you play them with other people actively. To help keep games playable by solo players who might not have a lot of friends, most developers end up making the social aspect of a game fixated on bonuses like gifts or on obtaining items that can be otherwise bought. This trend in game design makes Grab Games's Survivor World noteworthy, as it is a clear attempt at making a truly social game that only solo players with deep pockets could get far in by themselves.
