The best engine with regards to visuals is probably the Real Virtuality engine used by Bohemia Interactive for Arma games, you only have to look at the new Arma III screens to see that.
I managed to clock up around 15-20 hrs on single player before I had got all the items I wanted and had done a few builds. Once you have everything, there is little incentive to play unless with friends (which added another 20 hrs playtime). The good thing is that the devs are constantly adding new items in large amounts and are planning to add more bosses and even different gameplay modes in the long term which should be good.
It's a good game. If you've played Minecraft you will find they share some game mechanics although they are ultimately different. Terraria is more about exploration as opposed to building despite the masterpieces in the article and requires you to explore new progressively more dangerous environments in the search of new better items. It's definitely worth the small asking price and it plays well with friends.
I agree, this is slightly misleading as I thought it meant that AC:R will not be the last game in the current story arc as it is already known that it isn't the last for the franchise.
The Elder Scrolls V: Skyrim Deserved a mention in the article, however it would be unfair to change the current listings so it is listed in Honourable Mentions.
I'm sorry you don't like the list. I'm actually a PC gamer and have tried to include a wide mix of games including the console exclusives mentioned in the list. I apologise for the absence of Skyrim as it seems I may have accidently missed it during my research.
*embarassed at forgetting Skyrim. There's so many games coming out this year even I can't keep up with the releases lol. Sorry
Thanks for the feedback, I only started posting for the first time yesterday so am still fairly new to this.
It's not looking bad considering the games not due for a year though.
