"I had terrible experience with Sirius. I was one of their earliest clients (circa 2002) and found their gaming support to be quite terrible. The service was also heavily firewalled meaning that I could not play games such as Age of Empires II on the MSN Gaming Zone (which I used to play on a dial up!). Basically, I considered my 'Zip phase' to be a waste of taka 20,000, a considerable waste (especially considering that I was a student) that taught me some hard lessons. On a sidenote, in this country, being a technological laggard has its advantages.
But of course, I must also agree that the service (at least in its earlier stages, and I presume even now) was more geared toward providing a 'faster browsing speed' rather than 'good online gaming' which I was looking for. As such, caveat emptor (let the buyer beware). :)
In any case, I do wish my fellow Bangladeshi gamers the best of luck in finding a good ISP and a smooth connection to play online over!"
