Okay, y’all, some questions.  I’m a broke college student, I don’t have the couple hundred bucks to drop on a video game console, BUT I really want to try Dragon Age (this will entail me learning how to use a controller, because I’m a failure at that right now, and it’s very stressful to have someone try to ‘teach me’ rather than figuring it out on my own).  Now, I know DA is on Steam, but I also don’t have the money to drop on a computer designed for gaming.  Which brings me to my questions.

• Is Steam going to crash my computer and/or force me to get a new graphics card or whatever?
  
• Is Steam playable with computer controls, or is a controller mandatory?
  
• Is Steam going to make me significantly broker?
  
• Does Steam demand a high level of technological capability?
• Does anyone have other suggestions for a game an ADHD newbie with a fantasy obsession might enjoy?

Any answers you have would be very appreciated.

Obligatory question mark to make this answerable?
