First our picture. This is us getting killed on one of our golf cart runs. Feel the love. Catch some air. (Thanks to Mike for taking this sweet picture.)
Ah yes, the game that made me reinstall Crimsonland (which I registered). Evil Invasion is a fantasy themed Crimsonland minus the cool weapons, simple upgrade system, and fun.
One of the 2DNow forum users (DVDmanDT) turned me onto Liero as a good old low-res game. It's definitely pretty cool, with a huge amount of mods. I particularly like the 8-bit warfare mod where you can use all your old favorites. It had Mario's fire flower, Tapper root beer mugs, the Contra spread gun; Bomberman bombs. It even had a gun that launched the centipede from Centipede. Unfortunately, it crashes a lot, so I'll probably never spend much time with it. Also there was another game along the same lines that had a nicer mouse based control scheme. I wish I could remember the name.
DVDmanDT also mentioned C-Dogs as something to check out. If it didn't come so highly recommended, I wouldn't have looked twice at it. As it was I played the first couple levels and got painfully bored. Search room by room to find the keys to open the doors to the rooms with the stuff you need to blow up to complete the mission, then return to the start point. The isometric perspective is annoying because my bullets pass through the enemy much of the time. The slide move was cool (although some animation for it would have been cooler). Also, since I don't have DOS sound drivers, I had no sound. I'd call C-Dogs a decent game, but not a classic.
He also mentioned Shadows Over Riva which I had heard of, but I don't have time for RPGs.
