Shock horror, different opinion on the internet alert, but I actually think Pre-sequel is far superior to BL1. BL1 feels quite stale and empty. My order would be BL2, Pre-sequel/ BL 3 the same, BL1 last.
Out of all the games, pre-sequel is the one me and my son go back to most; we nearly skipped it, but persevered and ended up absolutely loving it. Once you get over its quirks, the low gravity and ground pound ability make it really really good fun (once you get past the boring opening missions).
Have put hundreds, possibly over a thousand hours into the games overall though, so this is a phenominal freebie for anyone who doesn't have these yet
Thanks. Just started the Pre Sequel with my son this morning, and we've enjoyed the first half hour. We loved BL2 so this Epic giveaway comes just at the right time.
