Haven't bought too many. Bastion, Transistor, and what has came with PS+. Also, Torchlight and Trine 1 & 2 if they count as indies.

I plan on buying Shovel Knight soon.

All the time.

Up next most probably: Armikrog, Satellite Reign, Valhalla Hills, Evoland 2, Sword Coast Legends, Sorcerer King.

I buy some at full price, but probably 95% of them, i wait for a big price drop on the PS Store.

Never.

If the game interests me, then yes.

My decision to buy an indie game is usually the same as buying a non-indie. It depends entirely on the game, and not on its indie status.

I'll usually snatch up just about every Metroidvania I can get my hands on, though.

No i dont buy Indies but im interested in Indies would be happy for recommendations

I buy lots of them , first couple years of the Wii U I bought 99.5% of them to support indie developers on WiiU. That said i have quite a few horrible games ... The Letter ... anyone

So long as the game is fun and there are no glaring issues, I buy it regardless of indie or AAA.
