I actually like spacing out the title bar, main buttons, and wall-o-texts. I can also agree with switching "Install" to Play
Quibbles:
1. I think some text on the tiles IS important. The Frontpage should sell people on the benefits of the FSO upgrade, and what the games are.
2. Individual buttons for all the TCs favours them above some of the stunning mods and campaigns that deserve equal billing.
3. Re: 2, a better layout would be 4 tiles arranged in a square: Buy FreeSpace 2, Upgrade to FreeSpace Open (Free!), Play FreeSpace 2 Mods/Campaigns (Free!), Play Standalone Games (Free!)
4. "Standalone" is an important distinction that should probably be in the title, or some other word. "Play Games" is too generic, and I don't support the idea of giving every TC its own button for reasons in 2. All the other products on HLP require FS2, so the distinction of "standalone" is, I think, needed if the consensus is consolidation.
5. If moving to the 4-tile format in a square, each tile could be larger and composed of a screenshot or multiple screenshots.
I also really happen to like the About Blurb you stuck in the banner. That's very HLP.
EDIT: Alternative if we want a button for each TC....
Divide the Tiles into two rows.
First row heading (small text): FreeSpace 2 Source Code Project and Mods
First row tiles: Buy FreeSpace 2 (Required for FS Upgrades and Mods), Upgrade to FreeSpace Open, Play FreeSpace Mods/Campaigns
Second Row heading (small text): Free Games (Standalone Games / Total Conversion Mods)
Second Row tiles: FOTG, WC, B5, Diaspora, WoD, etc.
That would give a top row of three large tiles for all things FreeSpace, and a bottom row of ~6? slightly smaller ones for each TC project. A small heading is unobstrusive, yet divides the two categories up so its clear what tile is for what kind of thing.
