So far I’ve just been checking out free games to get a feel for the system, but it looks like I have a 3 month pass for Horizon+ ready to activate, so I can try some other stuff once I have an idea what to start with.
I’ve been having some fun with Ironstrike and War of Wizards so far. I like the concept of the virtual CCG in Cards & Tankards, though it does seem like it’s going to try and bleed money like most “free” card battlers.
Try Graffiti. I made it specifically to be easy while still being fun, and I ended up making four more maps in that style (and the same artist) if you end up liking it.
Edit: Oh, and stay away from Ghost. That’s the polar opposite difficulty-wise =P
