Flash vs. Console

Most possibilities in a console game are far surpassing the ability of a flash game, but that does not mean the flash game will be less fun. Simplicity is something the mind enjoys.
My favorite console game just happens to have a relatively simple concept. Left 4 Dead has only four different levels. There is a possibility of only four characters and only a few weapons. Each level has its own obstacles, but over all there are only four special enemies, aside from the varying appearances of the simple zombies.
Finding a favorite flash game was much more difficult. All of the flash games are simple. Most are fun, for a while at least. The flash game that kept my attention for the longest though is a puzzle game. It's a spoof game on Portal. The character has a gun that creates two portals, a start point and an end point. The levels are ridiculously short at first but they get so difficult it takes true skill to reach the end.
