Because of the continuously expanding size of free MMORPG downloads, it isn’t a shock that there are now games and other MMOs which do not require gamers to download anything. As such, these games offer a great alternative to those players who do not wish to download such big files, effectively saving precious time and extending gaming time.
On the other hand, most people still prefer to play downloaded MMORPGs and would patiently wait for their game downloads to finish before they start to play. But what do these browser-based MMORPGs have against traditional MMORPGs?

Waiting Time
Since these browser-based games do not have to be downloaded and installed before playing, you actually wait less than when you want to start to play a full-fledged MMORPG. However, you may have less waiting time for downloads as opposed to downloading some 1-gigabyte game, but then you actually have to wait for it to download each time you want to play. Depending on your Flash settings, you might actually be downloading this browser-based game each time you open it. Simply put, browser-based games may make you download less but constantly, but with traditional ones, you just download once, with the exception of frequent patches and updates.

Play Almost Anywhere
Perhaps the most notable feature of these browser-based games is that you can play almost anywhere – even if you are not in front of your own PC. Should you want to play, just put on the link and voila – you can play. This is also quite helpful for those who have other operating systems than Windows such as Linux and Mac. All they need is a Flash-enabled browser, Internet connection, and they can enjoy playing with other people without the hassles of downloads.

Of course, you can also play your traditional MMORPGs on the go – pop them up into your USB flash drive, memory card or external hard drive, and play away.

Installation Issues
Traditional MMORPGs require you to install their game clients in your computer before you can actually play. This can be especially tricky if you have limited drive space. In addition, it can also be a nuisance if you are using somebody else’s computer (e.g. your mother’s or sibling’s.) Browser-based games do away with those installations, and you can play in just a matter of minutes – not hours of downloading and installing.
However, traditional MMORPG game clients run faster because they are installed right into your system. You do not have to wait each time the game loads in the browser while it downloads additional files. You get to have a more seamless game play, and faster response time.
Client-based MMORPGs are better for those who grind hard, while browser –based MMORPGs are better for those who play casually, or for the younger gamers.

In reality, it does not exactly matter as to how you want to play your MMORPGs. It always matters if and when you are having fun, regardless of whether you play on a stand-alone client or in the browser.
