VOTE CLOSES THURS 10PM UK TIME. The current round was quickly thrown together so the next will round will feature serious 'arcade' gaming; we have a triple vote with the winning three categories going to a final vote!
I've added a few games, please suggest more 
Selection 1
Lost in Space
There's tons of space games so we will take a few picks
Perhaps even Astro Droid will make it in after all those polls 
On the Grid
Games with grids or squares - mainly arcade games (could add a couple of puzzle games too?)
Java Jim, Kid-Grid
Water Slaughter
River Rescue... Salmon Run, River Raid 2K11 (the beer one that was suggested)
Selection 2
Hi-res Heaven
Hi-resolution (usually mono) games
Drol perhaps, there's lots to choose from here folks
The best games never before played in the HSC
Aquatron is my pick, awesome.
Bring on the Bugs
Bug based splattering, Bug Attack is fantastic...
Selection 3
Poie Position Team Round
Including 1 of the Pole Position versions with different tracks (despite bugs with the sign posts), and of course some individual points too
Clone Alone
A bunch of the best Clasic Game clones; so not the main titles, you know the sort
Can of Worms
Worm games
Nibbler?, Superwurm again there's a ton of them to pick from here
