Help a dood to choose a game D:

Out of these, I only played Transistor. Transistor is good.

i voted for HoMM6 because:

1. only played that game from you list
2. obviously i enjoyed it
3. i would have voted Transistor, but had a feeling it will get all the votes. and i didn't want HoMM6 to feel left out. (didn't checked before voting)
4. currently playing HoMM5 (from Steam), but they got a bundle at GOG. if you had HoMM3 on that list it should have won.
5. Potato of might and magic sounds better than Potransistor ;)

Axiom Verge is a great metroidvania, around 12-15 hours long.

Another game that I could recommend is Ys Origin, it's not a metroidvania by definition, but it's very close and it's a very fun action game with a lot of great boss fights and 3 different characters with their own style of play that make the game completely different on each playthrough.

(Voted FNV, long and great game)

I'd recommend unepic, it's hilarious, I think it lasts far more than 10 hours long (I've spent 28 h, but I'm not the fastest player) and if you want to complete every achievement it can become pretty challenging. Bonus: you may get it for some cards in the trade section.

A wide variety of genres you have listed there in the pool, which genre is your favorite?

Of all the metroidvanias on Steam, none of them are particularly long, but Valdis Story: Abyssal City is really good.

I've played Fallout New Vegas and Starbound from your list and I personally recommend Starbound. I've played over 120 hours in it and there's lots of cool stuff in it.

fallout NV is kinda expensive, knowing that sometimes was cheaper. Still a great great GREAT game.

Very diverse choices. I've personally played Banished, New Vegas and Transistor and you can't go wrong with any of them, really good games.

FNV Ultimate Edition from me, since I just bought it myself.
