While recent years have seen something of a resurgence in the number of mecha anime being produced, sales suggest that the genre has seen better days. Gundam SEED and Gundam SEED Destiny were best sellers in the first half of the last decade with 58,589 and 68,735 copies sold respectively. With a big drop off, nothing has broken 10,000 in 2010's. More after the jump.
Here's a fan video that gloriously does what it says on the tin. It provides a side by side size comparison of 174 mech, sorted by size from Microman to Lagann. Get a look after the jump.
