I'd like to revisit this, I'm trying to compile a good list for my Tips & Tricks column and have had great input from the forum - I'll be crediting you in the column if I can pull it together in time!
Here's what we have so far: Please add or dispute these entries if you can - I'm thinking the list should only include those games that would be a "7" or higher on a scale of 1-10.
