Haven't had much gaming time lately what with one thing and another, so I've put Halo aside for a while. I need to be a bit more focussed to play that, so I've been playing a bit more Defence Grid. Like you, Kieran, I didn't realise doing a mission on both Easy and Normal didn't count as two golds, so I'm a bit behind where I thought I was in going for 100 golds. Counted them up yesterday and I think I was at about 52 golds - which is a bit disappointing. (That might not be totally accurate - it's hard to be sure how many golds you have if you have to keep flicking between difficulties - and the achievement doesn't tell you you're XX% toward completion. Will almost certainly be around 50-60 though.)
Limbo became available yesterday afternoon, so I downloaded and played through that. Cracking game, and a bit longer than I remembered it, but still easily finished in a 2ish hour sesh.
Not sure whether to go back through it for achievements. I think I found about 3 or 4 of the ten or so hidden items playing normally. Could probably find another 2 or 3 if I went looking for them, or I could use a guide. Which I don't like to do - but these buggers are worth seventy gamerscore each.
Playing through the full game in one session with less than five deaths is a big ask, though.
Enjoyed Sunset Overdrive while it was briefly available. The game didn't really appeal to me all that much before, but it's more fun than I thought it'd be. Just a shame I didn't get much chance to play it before it was disabled.
Might pick it up next year, if I see it cheap.
Ditto Far Cry 4 and Assassin's Creed Unity. Loved FC3 and have enjoyed every AC game, so I'd like to play them both, but neither sounds deserving of full price.
