Let me introduce you to the universe of snes rpgs. It's an absolutely wonderful experience playing through some of these goodies. Snes= Super Nintendo and RPG= role playing game.
First, you'll need an emulator. An emulator is needed to run old snes games on your PC. You can find a good one here.
< snip >
Just take the latest version and download it (it's a legit site, no worries).
Then you'll need some games. Usually people google "snes roms" but if you download from coolroms you'll be fine. So google coolroms. I can't vouch for the legitimacy of the site, but I use firewall and stuff and downloaded from there for quite some time and never had issues.

Ok. So here you have a huge archive of old snes games to your disposal. The best snes rpgs are:
Chronotrigger
Seiken Densetsu 3
Tales of Phantasia
Lufia 2
Super Mario RPG
...but there are dozens more.
Ok, so now you have a bunch of files. What to do next?
Unzip them all. Winzip is a free evalution tool so google and download it if you don't have it. Then unzip them (really easy and legit, I promise).
Then open up zsnes. Time to set things up. Get to configure->video and find the best screensize for you. Then go to configure->input and click on set keys to set your keyboard keys. I use asdf for abxy, er for lr and then the arrows and enter and space for moving and pause.
Then use game->load and find a game you want to play. You can save and load up previously saved games by going game->load/save and you can have different save states meaning you can save in the same game 10 times (which is handy for boss battles and such).
The § key is also very handy because it fast forwards letting you grind faster

.
Well, there you have it. Have fun!
