It actrually depends on the game lol , usually most popular games are like around 40-50. To me i guess that is still an affordable price if you are willing to get that game, and it should be worth you money anyways.
New Pc games are probably made with better and higher graphics, meaning that they are made mostly for the newest grapic card there is and that means that it should be a new computer. With the new types of graphics and intesnse action i dont think 5 year old computers will be able to keep up
Yea i would not buy a gaming keyboard or a gaming mouse just to play games, a basic keyboard/ mouse would work fine for me, its practically the same thing lol . works the same
If i have the choice i would always play my games on windowed mode so i can do other things at the same time such as go on aim and talk to my friends lol . Or else my girlfriend gets mad if i ignore her >.>...
