GoldFire Studios has chosen to go in a completely different direction with BC Wars, which is in open beta as of today. Want to channel your inner caveman? You might want to take a little bit of time to check out this browser-based, free-to-play number. It's a bit predictable -- you start on Pangea and clams are the local currency -- but it definitely has possibilities. You began as a low level caveman, wearing a loincloth and scavenging for food, and have 200 steps (turns) you may take each day to advance your character.
Registration and character creation is quick and basic, and the game itself is a fun way to pass some time. Check it out here, explore the forest, and find some clams!
