Interesting, I have not looked at this for a while.
Increasing the sprite size? Your mad! Lol! I like the idea yet don't you think the sprite size is for a reason?
Don't quote me on this but I have experienced problems when increasing the size of tiles and how it effects the game. I mean, Fallout Tactics has a very small viewing window for loading visuals in game, and when you exeed the maximum I have found objects to disappear when scrolling off-screen. It is as though the viewing window itself is pretty much your area of loading graphics and objects that are attempting to show while centered way off screen simply cease to exist. Like I say, I'm not sure. But this may be a logical explanation for large objects disappearing when off screen.
Not trying to burst your bubble, it may be possible, but so could a moving tileset?
Nice sprites by the way diablo, today my task is to HARVEST THEM ALL!!! MUWAHAHAHA!!!!
