Simple Minecraft seeds are always nice. The spawn point for this seed is a small island with a number of tiny islands surrounding it. Just off the north-east coast is the mainland; it begins as desert, follow the shore around to the left and you will pass through swamp and black forest, then the land sprawls out into pine forest, birch forest, & mountains.
There is a small herd of horses on the spawn island, along with some good cave systems that have plenty of coal and iron to get you started.
The seed is: -1542404230
Since getting my new PC I have been playing using Optifine, a wonderific shader that adds lighting effects, realistic water, movement to plants, etc. It adds so much life to the game, and creates a beautiful and immersive experience. If you have a decent gaming PC, I highly recommend giving it a try, it's easy to install, and you can find the download HERE.
As for resource packs, Jolicraft still stands as my preferred pack. Colours are harmonious, and it creates a sense of unity and belonging within the world, nothing looks out of place or ugly. It's a low pixel pack, which I find charming, and it doesn't add much extra load for your computer to process. Get Jolicraft HERE.
