Retro Arcade Day

Today was a very retro day for the Xbox Live Arcade. Released were Xevious, a top-scrolling shooter, and Rush N' Attack, a side-scrolling beat 'em up. I tried each of their respective trials, and came away unimpressed. Granted, they are very old games, but they seem pretty bare-bones. Xevious in particular could really have benefited from a enhanced graphics version.
Unless you some fondness for either of the titles, I would stay away.
