you dont need to spend money if you dont want to. yes, i do drop money on the game from time to time, but there is a way to get your guys built up w/o having to spend cash. granted, it takes time, and a willingness to grind out the effort. make sure you have fast trainers, watch all the videos available (i think its about 100 videos per day. make sure to build up money,rests, and medical), and farm out the tokens. i only do token farming on the weekends, but you can get yourself 20 or more tokens each day.
