I just started a campaign on Indiegogo to make Monster RPG 2 free and open source! This is very exciting for me. On top of the game being free for everyone to download and play, the plan is to create a massive development wiki that allows game developers to use the engine to make games of their own with a large knowledge base to feed from. There are some pretty cool perks, so check it out: Monster RPG 2 Indiegogo Campaign.
