Seeing as it's almost the half-way point, I thought I'd provide an update:
Time Pilot 154,700.
Frogger 11,260. Like Donkey Kong, Frogger is on my bucket list of games to master. I still have a ways to go.
Ali Baba and 40 Thieves 17,900. This game is winning me over.
Nothing for Grobda yet. I've played it a few times but have gotten frustrated at so often blowing myself up by shooting an enemy tank that's too close to me.
