You do realise they're gonna cross-over at some point right? Thanos and the Infinity stones are a huge link between those two franchises and since they're building up to the Infinity Gauntlet, the GOTG and the Avengers will have to meet. I guess you'd be skipping that film assuming that happens, right?
thats what i feel i mean there is a HUGE blow out at the end you just see crazy destruction or thanos going in on these characters. i don't see everyone maybe 2 guardians show up or something i dunno.
