If you’re looking for an online RPG that won’t (or will) suck up your time, but aren’t looking to drop a lot of cash on some the more popular ones, give Dungeon Runners a try.

First, it’s free and so is the download, though for $5/month, you do get some benefits.

Second, it’s geared for the casual gamer, so you can spend 15 minutes running a dungeon and still feel like you accomplished something.

Third, loot is plentiful, which just adds to the sense of accomplishment.

It doesn’t have grand-scale immersible worlds, complicated quest lines (ala World of Warcraft), PVP is more of an arena or duel setting rather than open PVP and there’s no formal trading system (yet). However, if you’re looking for a free/low-cost MMO that won’t chew up a lot of your free time (unless you decide to let it), then DR just might be up your alley.
