But spending all day thinking up new computer games and finding ways to make the next version better can be hard!
Tony thinks good games are down to the little differences and attention to detail that developers put in.
Making a player like David Beckham actually look like Becks makes a big difference.
Even being able to see the detail in the crowds, and to see them move when a player is taking a throw in or a penalty makes a more realistic footie game.
People might not notice these little things straight away. But they certainly would if they weren't there, Tony reckons.
Future of gaming
There are loads of new games coming out all the time. But Tony reckons the biggest thing in the next couple of years will be online gaming.
Once internet connections get better, gamers will be able to play much more with others and share their information.
