I agree. Look at all the ripped TP trophies... I think it's a little bit of an overabundance. Some games/series in particular got very underrepresented. It's probably easier to rip models, but I'd like other series to have more trophy representation as well.
Metal Gear series always seemed odd to me (especially compared to the other 3rd party series: Sonic). Iirc, most trophies appeared in-game in some form (like Cardboard Box, Cypher, REX, etc.) except for Shagohod, arguably Iroquois Pliskin and Naked Snake... and leaving out many important people.
In fact, we got Iroquois Pliskin, which the description even mentions Raiden, but no Raiden trophy (only a sticker)!
I WILL see my bishounen cyborg ninja in Smash... somehow. Hopefully a trophy...
I hope.
