You keep using that word "free," I do not think it means what you think it means.
Seriously though, it's amazing how "free" games encourage people to spend more than you would on a full game. I hope they adopt a "pay once, or p2p" gaming model, and still pour the same amount of artistic talent, and enthusiasm into their games.
Also, I don't think I've played any "free" games that I've particularly enjoyed so far. The content is just never even slightly compelling. I mean, I like my games to be laden with emotional, brow sweating content. Is that too much to ask? "Free" games just don't cut it right now - They always feel like cheap knock-offs of the real thing.
