So the first list is Vertical Shooters - Click on it for a bigger version (and then you can probably magnify that also)...If you want to see what the columns mean, visit the first post of this blog ("About the Ratings").
PLEASE keep in mind that these are the best of the best at the top of my list. There are hundreds of games I've rated that fall below these games that aren't included in this list. This is just the highest tier of great games.
Click on the chart to make it larger... If it still isn't readable, right-click and choose "view image" - then you can zoom to full size.
