A threads of fate 2 would be awesome. I really enjoyed the first one and it teased a sequel after beating it with both characters. Also another medevil would be great, but I feel that it is more likely.
You don't need to put money into the game to do well. Watch Trump on youtube, and you'll learn what strategies/cards are effective. Taunt is a beginners trap, though it certainly has it's use. It's just that most cards that have it are bad. Look at the cards stat line, you want to double the card's mana cost with its stats until you can get some cards together that really combos well. If they don't add up their ability needs to pick up the slack. Card draw is usually worth between 1.5 and 2 mana depending on who you ask.
Unfortunately there are no hard and fast rules.
I'm currently in the top three of the Hearthstone Tournament here on Giant Bomb, without spending any money (Though I plan on buying Naxxramas). I'm using some slightly changed versions of Trump's Mage, Warlock, and Shaman free to play decks.
The Witcher for me. Once I connected the computer to the TV in the living room, gaming that doesn't use a controller took a hit. I'm in chapter 4, and have so far refused to play the Witcher 2 until I finish it.
