Explosions

[BlackJack47]

I would have to say either the Resi4/5 explosions or from blowing up any car in a game that needs you to unload bullets into it.

Prototype.

If that doesn't count, Mercenaries. It's awesome look, where you throw an airstrike on a skyscraper...

Hegemonia: Legions of Iron

Unfortunately I found only these two screenshots with good explosions:

Boom boom! [http://pcmedia.ign.com/pc/image/hegemonia_080202_002.jpg]

The screenshots don't do justice to the game's explosions.

Those look great, hadn't heard of this game, what genre?

4X, otherwise known as "eXplore, eXpand, eXploit and eXterminate" game, usually in outer space.

Far Cry 2 because if you blow a car up in a field you have a chance to make my second favorite thing FIRE!!!!!!!!!!!!!!!!!!!! that burns zebras

Resident Evil 5. Not the best game I've played but damn does it have pretty fire effects.

Any ratchet and clank game ever.
