The .info is still worthless but disregarding that simcheat.info would greatly limit your sites development and is worthless. pccheat.info has 2 c's in a row (which looks really wierd to me) but dispite that it is much better then simcheat.info because there are a lot of computer games, The Sims may be very popular but it accounts for a very small portion of the gaming industry.
I would definatly suggest developing them because alone they are probabally Low X (I mean LOW) but developed they could be worth a bit (depending on how you develop them)
For simcheat.info I would suggest not only cheats, but trainers, downloads (items and clothing and such, when you are able to do that), and forums, for each of the games.
For pccheat.info I would suggest that you again not only do cheats but trainers and possibally downloads (pending on games) and forums but not concentrated on 1 game (like just 1 forum for each game as an overall).
I'm totally new to domain buying and development, but I'm really looking forward to starting work on some of the names I've acquired over the past few months.
