No, no that's fine.
Oh, and do you mean you are
willing to pay? By the way, in the below paragraphs I've included the official website link to a game, as well as it's Wikipedia page.
Anyway, have you heard of Fable: The Lost Chapters? I have it, and when I was playing it, I thought it was great. The version I have is only about 2.7GB. Great storyline, great gameplay, great graphics, great everything. I'm not sure how much your brother will like it but I certainly enjoyed it. Microsoft Game Studios - Fable: The Lost Chapters

Heard of World of Warcraft? I've only played it a couple of times but from what I've seen, it's pretty good. It's an MMORPG which means it's a role playing game that lets you interact with other players over the internet. Thousands of people get addicted, so that must indicate that the developer is doing something right. World of Warcraft

Minecraft is a free indie flash game and although it looks quite simple and childish, once you get the hang of it, you're hooked. It's pretty much a pixelated game that is built around the player 'mining' blocks and making items out of them. Check out a few YouTube videos on it. Minecraft had me staring at the screen for hours every day for about half a year. I managed to make some amazing buildings. Anyway, I definitely recommend this one. Minecraft
