Base Wars - Cyber Stadium Series (USA) ROM

Base Wars combines baseball, robots, and violence into an 8-bit masterpiece that is fun whether you're into sports games or not. When your batter slides into second base and is tagged out, a fight begins between your robot and the baseman; if you win, you're safe, and if you lose, you're out. Each player can lose 3 or 4 fights before becoming disabled for the rest of the game.
The Season mode (I forget exactly what it terms itself) allows you to customize your robots, purchasing upgrades, new weapons, better armor, and other things, adding an extra layer of depth to what would otherwise be a very simple game. 
The graphics on field, and the little flashing square that represents the baseball, are pretty bad, even for the NES, but the combat sequences are sufficient. Comparing the baseball game itself to RBI Baseball (which is another I remember well) further confirms Base Wars' sub-par field graphics, but it is made up for, to an extent, by the combat.
It isn't a game that will eat up 40 hours of your time, but I remember it fondly from my childhood and would recommend it, if for nothing other than the experience, to avid retro-gamers. It's not the best NES game out there, but it certainly isn't the worse, and it can actually get pretty intense when the entire game hinges on a robot fight in the bottom of the 9th. 

This is my kind of sports game! No measuring the wind or micromanaging every limb on a player...just hitting and throwing a ball, maybe running in the field a bit, and when you think you were SO safe...you can fight for your base! It's really low-grade fighting, easily cheesed, but it feels good!

Controls were simple and responsive and the mechanics were easy to learn.

The sound was a bit repetitive and uninteresting.

The graphics on the field were chunky and lame...but on the mound! Wow! The robots looked amazing. My favorite part was that home runs zoomed out into space where the mother ship was located which makes sense as it's awesome motorcycle and UFO robots hitting these balls. They should be going into space!

Overall, this is a satisfying sorta-sports game to waste some time on.
