Since my life has been busier than normal and I'm in front of a computer a lot more.. I've turned to quick web browser based games and found them to be a lot of fun.
I'm playing a soccer manager at www.hattrick.org and an awesome american football sim at **** and I've been playing a lot of poker at www.pokerrpg.com.
These games don't require a ton of time and they are rewarding if you are intelligent and patient over a long period of time.
