I doubt that a site with a flash game can earn you significant amounts of money. Not unless it gets a huge amount of visitors.
You don't need to create a web site in English: AdSense is available for a number of languages so you could write quality content in one of those and have better chances at making money than by providing a game.
How much is much? There's virtually no limit. As much as your server can handle? Then your network of servers? It's about your satisfaction level. There's no too much traffic for Google, Yahoo, MSN and lots of second degree well established networks.
If you want to build a flash gaming site, go ahead. Do it. You will only know when you take it online and you will also improve your knowledge with every new site you build, what is priceless.
