Seriously... why 4 ET games? lol
There can be multiple reasons:
1. Collect enough copies to build a house out of them (or a "House of Fail" if you will).
2. HUGE E.T.-burning bonfire.
3. Collect ALL the copies, have a monopoly and then sell them all for ridiculous prices (hehehe...).
4. For the same reason I try to find cheap copies of Shaq Fu and Superman 64 or other bad games (AKA lulz).
Really though, only one of them is a copy I bought, one of them was free, and 2 others were in a huge bundle (that included a vectrex and atari 7800 and 40 other atari games).
Props for having the Frankensystem hooked up 24/7. That reminds me that I still need to find a 32X!
Frankensystem indeed, that was a hassle to even figure out how to hook it up. I tend to keep the AC adaptors NOT plugged in though, since they take too much space, I plug them in only as needed.
