Verdict: This is the trio of companion games that, together, made the Pokemon series a commercial force of nature virtually overnight.
These titles established the formula that has proven immensely successful ever since (namely the notion of "Gotta catch 'em all!"), and in a move that was wildly ahead of its time, allowed multiplayer Pokemon trading and battles thanks to the Game Boy's Game Link Cable.
While the graphics and audio were never much to shout home about, this is a prime example of gameplay trumping presentation, the highly addictive mechanics essentially defining the Pokemon experience from this moment on.
