[Multiplatform] Quality in the Bargain Bin

Dai Senryaku VII: Exceed - $19.99 new (PS2)
Released in 2005 for Xbox (under the name Dai Senryaku VII: Modern Military Tactics), I picked up the game for 20 bucks. Ported over to the PS2 with some new additions, it's an absolutely fantastic strategy title that has an assload of strategic variables and even logistics to consider. It's definitely one of the harder and more rewarding titles in the genre, let me tell you! Examples:

Total unit types: Over 400
Total terrain types: 26

The game even has depths for each tile (like deep sea, lower atmosphere, upper atmosphere), so multiple units can be stationed on a single tile. Crazy stuff. The game's AI tends to rely a bit too much on copters, but it still puts up a good fight.

As I mentioned before, it was also released for the Xbox (and is backwards-compatible with the 360) and runs about 8 bucks used, so even 360 fans really should try it out if they find it.

Jam it back in, in the dark.

Actually, the PS2 version is almost universally considered the worse of the two because of its absolutely horrendous load times. It's barely considered playable.

There's nowhere I can't reach.
