I loved the C64 game, but this updated version looks really ugly. Is it possible to play all of it with the old graphics?

Actaully, the trailer states that the classic version is included, and even shows the old school graphics running (around the 1:15/1:16 mark).
I would love the original and Boulderdash II on DOS but at least this version is doing some fan service.

If drawing the next card(s) in War makes it interactive, then reading regular books is an interactive form of storytelling because if the reader doesn't interact by switching pages then the story doesn't progress. If that doesn't work as a definition of interactive fiction, then it shouldn't work for interactive gameplay.
Do you also think War is a game where players have meaningful gameplay choices, since they can choose to stop playing?

Same. Played the game on GameBoy, and it looked nicer than this. Weird. Too much flashy crap going on.

I own that one, still think it would be better to go with a more 2D art style for this type of game.

They would have been better off doing the Nintendo version with added levels. Even the old classic version looks better than this so-called adaptation for a newer generation.

Unfortunately the game card does not tell if the original version is included, especially as the new version does not come with Linux support.

The original levels are included; it's not a separate game. Your character is a customizable avatar with various hats/faces/clothes/etc., but you can just ignore all that nonsense and choose a voxel version of the original character instead, which makes the game a lot less off-putting. It's absolutely a mobile game port, but again you can completely ignore all the mobile junk (unlock things to make your character go 2% faster wooooo!) and just play it normally. If you like the original I'd say it's worth the $10 sale price for a couple hundred Boulder Dash levels but I wouldn't pay any more than that.

This feels like you're changing the definition of "interactive". Are you saying War is interactive only due to the interaction with the other player, not the interaction with the game? A single-player version of War, where the player draws cards from their own deck, and operates a dummy player that works by randomly drawing cards from its deck... won't be interactive, then?
Games are interactive when something a player does can affect the game state. Merely deciding to stop what you're doing doesn't count, or things like reading a book or watching a move would be interactive. The ability of another person to stop what you're doing also doesn't count, otherwise watching a movie is affected by weak interaction with your electric company, and maybe your internet or streaming provider, so is it interactive then?

War doesn't need two separate players.

You can play against yourself, acting like both players, and since neither player has any decisions to make, and there's no skill component, there are no issues with doing so and the game will have the same outcome.

For that matter, it isn't hard to program a computer to play the game with itself. You run the program, and the program plays the game all by itself, with no human input, and no AI needed either.

Wait I remember this.....

Heh. Yet another one ugly 3d clone of the old classic game.

Good to see Boulder Dash back, not sure about the graphics.

I dunno, I still prefer the look of the Deco/Victor port over the original Rockford.

Even if it does commit the sacrilege of playing far smoother than Boulder Dash should.

I prefer the look of the original; but that's just nostalgia talking I think.
